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

purposeObesity has been reported to be associated with short sleep duration. It follows that patients with a BMI >35kg/m MATERIALS AND

methodsSleep duration and quality, using the Pittsburgh Sleep Quality Index (PSQI), was analysed in 203 patients undergoing bariatric surgery between June 2016 and May 2019 in a single centre. Anthropometric data on all patients were recorded as well as presence of OSA and PAP usage.

resultsThe bariatric population reported an average (standard deviation) sleep duration of 6.5 (1.6) h, and 67.9% of patients had a documented poor sleep quality (PSQI>5). The presence of OSA did not significantly influence either sleep duration (p=0.23) or sleep quality (p=0.5). On logistic regression, there was no significant relationship between sleep duration or sleep quality and the following variables: age, sex, and AHI. There was however a significant association between BMI and sleep quality (p= 0.007). PSQI was inversely associated with BMI. This equated to 1 kg/m

conclusionsThe presence of OSA does not influence either sleep duration or sleep quality in the bariatric surgical population. This suggests that clinically severe obesity itself may cause poor sleep.
