Three-year effects of bariatric surgery on obstructive sleep apnea in patients with obesity grade 1 and 2: a sub-analysis of the GATEWAY trial.
Trial report in International journal of obesity (2005), 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 21 papers, 1 of them a synthesis that pooled 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundMost of the evidence on bariatric surgery on obstructive sleep apnea (OSA) is based on observational studies and/or short-term follow-up in patients with obesity grade 3. SUBJECTS/
methodsThis randomized study compared the effects of roux-en-Y gastric bypass (RYGB) or usual care (UC) on OSA severity in patients with obesity grade 1-2. Mild, moderate, and severe OSA was defined by the apnea-hypopnoea index (AHI): 5-14.9; 15-29.9, and ≥30 events/h, respectively. OSA remission was defined by converting any form of OSA into normal AHI (<5 events/h).
resultsAfter 3-year of follow-up, the body-mass index increased in the UC while decreased in the RYGB group: +1.7 (-1.9; 2.7) versus -10.6 (-12.7; -9.2) kg/m
conclusionsRYGB is an attractive strategy for mid-term OSA remission or decrease moderate-to-severe forms of OSA in patients with obesity grade 1-2.
