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

Objective: The influence of extreme sleep duration on coronary heart disease (CHD) risk across genders remains a debated topic. Methods: This analysis gathers observational studies that explore association between varying sleep durations and CHD risks. Trend estimation employs generalized least squares, converting specific category risk estimates into relative risks (RR) per hour of sleep increase. A two-stage hierarchical regression model evaluates potential linear dose-response relationships. Data analysis utilizes random-effects restricted cubic spline models with four knots. Results: Involving 17 studies and 906,908 participants, this meta-analysis identifies a pronounced U-shaped nonlinear relationship between sleep duration and CHD risk applicable to both genders ( Conclusion: The influence of sleep duration on CHD risk differs significantly between genders.
