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.

2 · The registry

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

purposeDespite a high prevalence of obstructive sleep apnea (OSA) in patients undergoing metabolic and bariatric surgery (MBS), there is no consensus on the best perioperative OSA strategy. Supplemental oxygen therapy without pre-operative OSA-testing (pulse oximetry) is safe and more cost-effective compared to preoperative OSA-testing using poly(somno)graphy (sleep test). This study aimed to compare these strategies on excess daytime sleepiness (EDS), its impact on daily functioning and health-related quality of life (HRQoL).

methodsMulticenter prospective cohort study including 1388 patients, 691 in the sleep test and 697 in the pulse oximetry group based on local protocols. EDS (ESS), its impact on daily functioning (FOSQ-10), HRQoL (RAND-36) and total weight loss (TWL) were assessed preoperatively and 1, 3, 6 and 12 months postoperatively. (Sub)scores were compared over time between and within groups using linear mixed models.

resultsNo differences between the pulse oximetry and sleep test strategy were found in EDS, its influence on daily life and HRQoL, and all improved after MBS. In the pulse oximetry group a lower TWL was found 1 month postoperative (-0.7%).

conclusionConsidering that pulse oximetry is more cost-effective, equally safe and comparable in EDS, its effect on daily functioning and HRQoL and no clinically relevant difference in TWL was found compared to the sleep test strategy, this study lends further support for pulse oximetry being the best strategy for managing OSA in patients undergoing MBS.
