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

backgroundThis research investigated the combined influence of sleep duration and sleep difficulty on suicidal ideation in the general populace.

methodsNational Health and Nutrition Examination Surveys (NHANES) datasets from 2005 to 2018 were utilized in a cross-sectional study. Details on sleep duration, sleep difficulty, and suicidal ideation were accumulated using sets of questions. Sleep duration was segmented into short (≤ 6 h), optimal (6–9 h), and long (≥ 9 h). Multiple logistic regression models were utilized to analyze the links between sleep duration, sleep difficulty, and suicidal ideation, with multiplicative and additive interactions being examined.

resultsAmong the 24,703 participants, the weighted percent suggested that 3.2% reported suicidal ideation. Outcomes of the fully-adjusted designs suggested: (1) A U-shaped organization was observed between sleep duration and suicidal ideation, with both short sleep duration (OR = 1.40, 95% CI: 1.17– 1.67) and longer sleep duration (OR = 1.99, 95% CI: 1.46– 2.72) showing a boosted probability of suicidal ideation, (2) self-reported sleep difficulty confers 2.6-fold greater probabilities of suicidal ideation independent of sleep duration (OR = 2.67, 95% CI: 2.17– 3.28), and (3) the co-occurrence of longer sleep duration and sleep difficulty interactively enhanced suicide ideation risk (RERI = 1.24; AP = 0.28), accounting for 28% of suicidal ideation cases.

conclusionsBoth quantitative (sleep duration) and qualitative (sleep difficulty) problems individually and jointly boost suicidal ideation danger. Our study suggests that incorporating multidimensional sleep health assessments could enhance suicide prevention protocols.
