Risk of bias

Bias

Authors' judgement

Support for judgement

Random sequence generation (selection bias)

Low risk

The allocation sequence was block randomized and generated independently of the research team.

Allocation concealment (selection bias)

Low risk

Allocations were placed in sequentially numbered sealed opaque envelopes.

Blinding of participants and personnel (performance bias)
All outcomes

Low risk

Open label trial, however temperature is an objective measurement that should not be subject to bias from lack of blinding.

Blinding of outcome assessment (detection bias)
All outcomes

Low risk

This was an open label trial, however temperature is an objective measurement that should not be subject to bias from lack of blinding.

Incomplete outcome data (attrition bias)
All outcomes

Unclear risk

No reasons given for missing data or patients withdrawn.

Subjects withdrawn or missing data: combined 9%, ibuprofen 14.7%, paracetamol 9%.

Selective reporting (reporting bias)

High risk

  • Study did not report mean temperatures at hour 2 as initially stated: "Too few children had data at two hours to allow meaningful comparison, as they had already been discharged home."

  • "Secondary outcome analysis of the time spent on the unit did not add to our findings and is not reported."

  • Mean fall from T0 to T1 was reported but not stated as an outcome measure.

Other bias

Unclear risk

Potential baseline imbalance: higher proportion of patients in combined group were admitted to hospital compared with other groups.

Hay 2008

Risk of bias

Bias

Authors' judgement

Support for judgement

Random sequence generation (selection bias)

Low risk

Randomization sequence was generated via a remote, automated telephone service provided by the Health Services Research Unit at the University of Aberdeen.

Allocation concealment (selection bias)

Low risk

After written informed consent had been obtained and the baseline questionnaire completed, the research nurse telephoned a remote, automated randomization service.

Blinding of participants and personnel (performance bias)
All outcomes

Low risk

Study medication identity was concealed.

Blinding of outcome assessment (detection bias)
All outcomes

Low risk

Research nurse was blinded to process.

Incomplete outcome data (attrition bias)
All outcomes

Unclear risk

Article did not address why three patients (one from ibuprofen and two from ibuprofen plus paracetamol group) had missing data for time without fever. "Attrition was minimal."

"Thus, children were omitted from analyses only if none of the data required were available, and as these were so few in number the influence of missing data on the intention‐to‐treat analyses was negligible."

Selective reporting (reporting bias)

Low risk

All assessed outcomes were reported.

Other bias

Low risk

The possibility of receiving either or both drugs combined and the severity of the child's illness may have influenced parental decision to participate.

Disclosure: first author has been a paid consultant for the Consumer Healthcare Products Association, McNeil Consumer Healthcare, Novartis Consumer Health, Inc., Procter & Gamble, and Reckitt Benckiser Healthcare International Ltd., but no industry employees were involved in any aspect of the study.

11 patients participated ≥ 2 times (maximum 3 times).

Risk of bias

Bias

Authors' judgement

Support for judgement

Random sequence generation (selection bias)

Low risk

Each child was randomly assigned to 1 of 3 treatment groups according to a computer‐generated log.

Allocation concealment (selection bias)

Unclear risk

Not specified.

Blinding of participants and personnel (performance bias)
All outcomes

Low risk

No attempt was made to blind the participants, however temperature is an objective measurement that should not be subject to bias from lack of blinding.

Blinding of outcome assessment (detection bias)
All outcomes

Low risk

No attempt was made to blind the research nurses, however temperature is an objective measurement that should not be subject to bias from lack of blinding.

Incomplete outcome data (attrition bias)
All outcomes

Low risk

No loss of participants during the study.

Selective reporting (reporting bias)

Low risk

All assessed outcomes were reported.

Methods

Study design: randomized, double‐blind, parallel‐group trial.

Study dates and duration: September 2003 to March 2004.

Method of temperature measurement: rectal glass and mercury thermometer.

Time points measured in study: daily temperature diary (parents asked to measure rectal temp at least 3 times daily during tx then once daily x 10 days), telephone interview at 24 hours and 48 hours, office visit day 3, 5, 10, and 14 day follow up evaluation.

Participants

Number: 480

Number of patients in each intervention: 160 in each of the 3 groups.

Inclusion criteria: all consecutive children aged 6 ‐ 36 months who had rectal temperature ≥38.4 °C.

Exclusion criteria: not attending daycare centers, had taken temperature‐altering drugs or antibiotics within 10 days before presentation, known abnormal liver or renal laboratory values, medical history of renal or hepatic impairment, gastrointestinal bleeding, known allergy to any antipyretic, congenital or acquired immunodeficiency, Reye syndrome, asthma, bronchiolitis or malignancy, and children whose caregivers were unable to apply the NCCPC to measure stress.

Baseline characteristics:

  • Age months (SD): paracetamol 18.6 (8.72), ibuprofen 19.5 (9.09), paracetamol plus ibuprofen 19.3 (9.29)

  • Sex male (%): paracetamol 71 (46%), ibuprofen 73 (40%), paracetamol plus ibuprofen 62 (38%)

Interventions

Group1: paracetamol (12.5 mg/kg) q6h, max 50 mg/kg/day); half of the group received initial loading with paracetamol (25 mg/kg) and the other half received initial loading with ibuprofen (10 mg/kg)

Group 2: ibuprofen (5 mg/kg) q8h, max 20 mg/kg/day; half of the group received initial loading with paracetamol (25 mg/kg) and the other half received initial loading with ibuprofen (10 mg/kg)

Group 3: paracetamol (12.5 mg/kg/dose, max 50 mg/kg/d) alternating with ibuprofen (5 mg/kg/dose, max 20 mg/kg/d) q4h; half of the group received initial loading with paracetamol (25 mg/kg) and the other half received loading with ibuprofen (10 mg/kg)

Outcomes

Primary:

  1. Body temperature

  2. Stress score

  3. Amount of antipyretic used at the 3 day time point (number of doses)

Secondary:

  1. Total days that a primary caretaker had to stay home from work because the infant could not attend daycare because of illness

  2. Recurrence of fever (≥37.8 °C) within 5 and 10 days after initiation of treatment

  3. Number of emergency department visits within 10 days of enrolment

  4. Hepatic and renal function

  5. Appearance of gastrointestinal symptoms or bleeding

Notes

Location: Central Israel

Setting: multi‐Centre; three primary paediatric community ambulatory centers.

Risk of bias

Bias

Authors' judgement

Support for judgement

Random sequence generation (selection bias)

Low risk

"Computerized random number generator to stratify according to the center in blocks of 60 numbers so that each block comprised 20 patients randomly assigned to each treatment group, with 10 patients assigned to each loading medication."

Allocation concealment (selection bias)

Low risk

Admitting nurse used a computerized random‐number generator and handed the parent or guardian a sealed opaque folder holding 3 sealed envelopes: 1 containing an advice sheet explaining the physiology of fever and its nonpharmacologic management; 1 containing the prescription for the loading medication; and 1 containing the drug prescription.

Blinding of participants and personnel (performance bias)
All outcomes

Unclear risk

Parents were described as being blinded, but the differences in drug regimens and lack of placebos in the single agent arms suggest that blinding is unlikely.

Blinding of outcome assessment (detection bias)
All outcomes

Low risk

"All of the children were evaluated and followed up by the same physician (E.M.S.), who was blinded to the group allocations (as were the parents or guardians)."

Incomplete outcome data (attrition bias)
All outcomes

Low risk

A total of 480 infants met the eligibility criteria, of whom 464 (96.7%) completed the study. Of the 16 infants (3.3%) who withdrew from the study, 7 (1.5%) failed to return for follow‐up visits within the first 10 days, and 9 (1.9%) did not return for laboratory evaluation after symptoms were alleviated.

Selective reporting (reporting bias)

Unclear risk

No significant differences found with different loading medications, so patients were grouped according to maintenance medication. Data for outcomes from different loading medication groups were not reported.

Comment on PITCH trial

Lal 2000

No mean temperature or proportion afebrile data published, despite being measured. Thus, study was at high risk for selective outcome reporting bias. Author was contacted and did not have access to original data. No quality of life indices examined.

1 Downgraded by 2 for risk of bias: in this study mothers collected the data on NCCPC scores and were unblinded to allocation. In addition, in this study the mean number of doses of medication was actually lower in the group allocated to alternating treatment. The reasons for this are unclear as logically they should receive more doses.

*The basis for the assumed risk (eg the median control group risk across studies) is provided in footnotes. The corresponding risk (and its 95% CI) is based on the assumed risk in the comparison group and the relative effect of the intervention (and its 95% CI).
CI: Confidence interval; RR: Risk ratio.

GRADE Working Group grades of evidence
High quality: further research is very unlikely to change our confidence in the estimate of effect.
Moderate quality: further research is likely to have an important impact on our confidence in the estimate of effect and may change the estimate.
Low quality: further research is very likely to have an important impact on our confidence in the estimate of effect and is likely to change the estimate.
Very low quality: we are very uncertain about the estimate.

1 This single study was conducted in the USA.
2 Downgraded by 1 for risk of bias: this study was at unclear risk of selection bias as allocation concealment was not described.
3 Downgraded by 2 for very serious imprecision due to the very small sample size.
