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

The Pediatric Daytime Sleepiness Scale (PDSS) is a common tool for assessing daytime sleepiness in children and adolescents. Despite its widespread use, its internal consistency reliability across populations and cultures is still being assessed. This meta-analysis synthesizes data from multiple studies to assess the PDSS's internal consistency. A comprehensive review of 18 databases was conducted to gather studies examining the reliability of PDSS using Cronbach's alpha. A random-effects model was employed to calculate the overall Cronbach's alpha, while the I Supplementary Information: The online version contains supplementary material available at 10.1007/s41105-025-00603-x.
