[Hemorrhage rates following coblation tonsillectomy. A meta-analysis of published trials].
Synthesis in HNO, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundWith over 100,000 cases annually, tonsillectomy is one of the most frequently performed ENT surgical procedures in Germany. Hemorrhage ranks among its serious postoperative complications. In this systematic review, we analyze hemorrhage following tonsillectomies performed using coblation technique.
methodsOf the 135 studies identified, 38 could be included in the analysis, most being prospective randomized controlled studies. Data from 6290 patients were gathered.
resultsOf all tonsillectomies performed, hemorrhages occurred in 355 patients. Of these, 256 cases could be classified as 41 primary and 215 secondary hemorrhages. Overall, the total hemorrhage rate for the coblation procedure was 4.9% (95%-CI: 0.044-0.054) for the fixed effects model.
conclusionSignificantly higher rates of postoperative hemorrhage were found in a few studies, yet they were well above the 95% confidence interval of 4.4-5.4% of the literature. These studies could possibly be interpreted in terms of an autodidactic learning process. As with any surgical technique, proper training is essential.
