Characteristics of studies

Characteristics of excluded studies [ordered by study ID]

Study

Reason for exclusion

Jensen 1991

ALLOCATION:
Randomised controlled trial, non‐blinded

PARTICIPANTS:
54 patients with recurrent acute tonsillitis (> 3 episodes in the previous 2 years)

INTERVENTIONS:
150 mg clindamycin 4 times a day for 10 days versus no antibiotic treatment (no placebo used). 28 of the included patients in both arms had a tonsillectomy within the 1‐year period
Excluded because no placebo used and tonsillectomy was used for treatment before follow‐up was complete

Liltholdt 2003

ALLOCATION:
Randomised controlled trial, blinded

PARTICIPANTS:
110 patients (adults and children) with recurrent acute tonsillitis (> 3 episodes in the past 2 years)

INTERVENTIONS:
Azithromycin 500 mg or placebo once a week for 6 months. If any patient had confirmed acute tonsillitis, it was considered failed treatment and they were offered tonsillectomy
Excluded because tonsillectomy was used as treatment before follow‐up was complete

Mora 2003

ALLOCATION:
Randomised controlled trial

PARTICIPANTS:
180 children with recurrent pharyngotonsillitis (at least 3 episodes in the past year)

INTERVENTIONS:
Cefpodoxime proxetil (100 mg twice a day, 6 days a month for 6 months) versus placebo

OUTCOMES:
Authors reported that cefpodoxime may be effective in reducing symptoms of recurrent pharyngotonsillitis and preventing recurrences
Excluded because the results were uninterpretable; we made numerous attempts to contact the investigators but received no response

Sirimanna 1990

ALLOCATION:
Randomised controlled trial, non‐blinded

PARTICIPANTS:
Patients with recurrent tonsillitis (> 4 attacks in the past year)

INTERVENTIONS: intramuscular dose of benzathine penicillin each month for 6 months versus no treatment
Excluded because no treatment was used as a comparison
