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

To examine whether the effects of low sleep quality, sleep deprivation, and chronotype on daytime cognitive function varied by age group. All data were collected online. We obtained the data from 366 employed people in their 20s, 40s, or 60s. The participants were required to fill out a questionnaire comprising of the Pittsburgh Sleep Quality Index, an Ultra-Short Version of the Munich ChronoType Questionnaire, and Karolinska Sleepiness Scale, and perform the online Stroop task through the web browser on their own PC. The results of analyses of variance showed that people in their 20s had more of an evening chronotype, while those in their 20s and 40s experienced more sleep loss than those in their 60s. Stroop interference, reflecting decline in selective attention, was greater in people in their 60s. The results of structural equation modeling showed that sleep loss tended to relate to lower Stroop interference in people in their 20s. Additionally, people in their 60s exhibited a significant relationship between lower sleep quality and lower Stroop interference in the reaction time. At least in this study, interindividual differences in sleep loss, chronotype, and sleep quality did not have a strong effect on cognitive function measured using the online Stroop task in the 40s age group. However, people in their 20s with sleep loss and those in their 60s with lower sleep quality showed higher selective attention, the mechanism of which requires further research.
