Trial report in BMJ (Clinical research ed.), 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT00136877 (Effect of Tonsillectomy on Preventing Recurrent Streptococcal Throat Infections), which is not on this map. Cited by 32 papers, 5 of them syntheses that pooled it.

1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Abstract

objectiveTo determine the short term efficacy and safety of tonsillectomy for recurrent streptococcal pharyngitis in adults. Design Randomised controlled trial.

settingAcademic referral centre in Finland.

participants70 adults with documented recurrent episodes of streptococcal group A pharyngitis.

interventionInstant tonsillectomy (n=36) or remaining on waiting list as control (n=34).

main outcome measuresPercentage change in the risk of an episode of streptococcal pharyngitis at 90 days. Rates of all episodes of pharyngitis and days with symptoms and adverse effects.

resultsThe mean (SD) follow-up was 164 (63) days in the control group and 170 (12) days in the tonsillectomy group. At 90 days, streptococcal pharyngitis had recurred in 24% (8/34) in the control group and 3% (1/36) in the tonsillectomy group (difference 21%; 95% confidence interval 6% to 36%). The number needed to undergo tonsillectomy to prevent one recurrence was 5 (3 to 16). During the whole follow-up, the rates of other episodes of pharyngitis and days with throat pain and fever were significantly lower in the tonsillectomy group than in the control group. The most common morbidity related to tonsillectomy was postoperative throat pain (mean length 13 days, SD 4).

conclusionsAdults with a history of documented recurrent episodes of streptococcal pharyngitis were less likely to have further streptococcal or other throat infections or days with throat pain if they had their tonsils removed.
