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.

Abstract

objectiveBariatric surgery has been suggested to improve obstructive sleep apnea (OSA) in short-term studies, but long-term evidence is limited. We evaluated remission and new onset of OSA over 20 years in participants from the Swedish Obese Subjects (SOS) study, comparing bariatric surgery with usual obesity care.

methodsThe SOS study is a nonrandomized, controlled intervention study including 4047 individuals who received bariatric surgery (n = 2010) or usual obesity care (n = 2037). OSA status was assessed via questionnaires at baseline and at 1, 2, 3, 4, 6, 8, 10, 15, and 20 years. We examined remission and new onset of OSA among participants with or without the condition at baseline, comparing surgery to usual care.

resultsOn average over 20 years, bariatric surgery was associated with a 32.1 percentage points lower prevalence of OSA in participants with baseline OSA (95% CI: -36.9 to -27.2; p < 0.001) compared to usual care. Among those without baseline OSA, surgery patients had a 5.8 percentage points lower prevalence of new-onset OSA (95% CI: -7.1 to -4.6; p < 0.001).

conclusionsBariatric surgery was associated with durable OSA benefits, including higher remission and lower long-term new onset of OSA compared to usual obesity care.
