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

purposeTo evaluate the relationship between body weight and daytime sleepiness (DS) in patients with obstructive sleep apnoea (OSA).

methodsWe prospectively evaluated 353 untreated patients with OSA, categorised by body mass index (BMI) as normal weight, overweight, grade 1, grade 2, or grade 3 obesity. Patients with OSA and obesity hypoventilation syndrome (OHS) were analysed as a separate group. Demographic and anthropometric data, nocturnal polygraphy parameters, and DS (by the Epworth Sleepiness Scale-ESS) were collected. Excessive DS was defined as ESS > 10.

resultsPatients were classified as normal weight (13%), overweight (26%), grade 1 obesity (28%), grade 2 obesity (16%), grade 3 obesity (6%), and OHS (11%). DS did not differ significantly across body weight categories, whereas patients with OHS exhibited higher ESS scores and a greater prevalence of excessive DS.

conclusionIn patients with OSA, DS is not related to body weight or obesity per se. Instead, disease severity and the depth of nocturnal hypoxaemic events were the main determinants of excessive sleepiness, particularly in patients with concomitant OHS.
