During the time of this taking place, the physician and patient were positioned so that neither could see the nurse's face nor the material she injected. Thus, neither had any direct information concerning what was injected and, practically speaking, had no contact with the only person who knew"

Intention‐to‐treat analysis performed? Pain

Low risk

All randomised participants included in the analysis. Quote: "All patients were seen 1 wk, 4 wk, 6 wk and 8 wk post‐injection except those whose pain scores at any subsequent evaluation were the same as their pre‐treatment scores; they were not seen further. It was assumed that their scores would no longer improve and they were counted as remaining at their pre‐treatment level throughout the experiment".

Risk of bias

Bias

Authors' judgement

Support for judgement

Random sequence generation (selection bias)

Unclear risk

Method used to generate random sequence of allocation was not reported, so the risk of selection bias was unclear

Allocation concealment (selection bias)

Unclear risk

Method used to conceal the random sequence of allocation was not reported, so the risk of selection bias was unclear

Blinding of participants?

Unclear risk

It was unclear if method used to blind participants was appropriate

Blinding of health care provider(s)

Unclear risk

Physicians were not explicitly described as blinded, so the risk of performance bias was unclear

Intention‐to‐treat analysis performed? Pain

Unclear risk

It was unclear whether all participants randomised were also analysed

Intention‐to‐treat analysis performed? Function

*The basis for the assumed risk (e.g. the median control group risk across studies) is provided in footnotes. The corresponding risk (and its 95% confidence interval) is based on the assumed risk in the comparison group and the relative effect of the intervention (and its 95% CI).
CI: confidence interval; NNTB: number needed to treat for an additional beneficial outcome; RR: risk ratio; SMD: standardised mean difference; VAS: visual analogue scale; WOMAC: Western Ontario and McMaster Universities Arthritis Index

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 Median reduction as observed across placebo groups in large osteoarthritis trials (see methods section, Nüesch 2009).
2 SMDs were back‐transformed onto a 10‐cm visual analogue scale (VAS) on the basis of a typical pooled standard deviation (SD) of 2.5 cm in large trials that assessed pain using a VAS and expressed as change based on an assumed standardised reduction of 0.72 SD units in the control group.
3 Percentage of improvement was calculated based on median observed pain at baseline across control groups of large osteoarthritis trials of 6.1 cm on 10‐cm VAS (Nüesch 2009).
4 Absolute response risks for pain in the control groups were assumed 31% (see methods section).

5 SMDs were back‐transformed onto a standardised Western Ontario and McMaster Universities Arthritis Index (WOMAC) disability score ranging from 0 to 10 on the basis of a typical pooled SD of 2.1 in trials that assessed function using WOMAC disability scores and expressed as change based on an assumed standardised reduction of 0.58 SD units in the control group.
6 Percentage of improvement was calculated based on median observed WOMAC function scores at baseline across control groups of large osteoarthritis trials of 5.6 units (Nüesch 2009).
7 Absolute response risks for function in the control groups were assumed 26% (see methods section).
8 Median control risk across placebo groups in large osteoarthritis trials (see methods section, Nüesch 2009).

9 Downgraded (2 levels) because: Most studies that reported this outcome are of high or unclear risk of bias, and statistical heterogeneity is large.

10 Downgraded (3 levels) because: 50% or more of the studies that reported this outcome are of high or unclear risk of bias, and the confidence interval of the pooled estimate is wide and includes the null effect.
