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

STUDY

objectivesShort and long sleep durations have been found to be associated with chronic conditions like diabetes mellitus, hypertension and cardiovascular disease. However, most studies were conducted in developed countries and the results were inconsistent. The aim of this study is to investigate the association between sleep duration and self-reported health status in a developing country setting.

methodsWe conducted secondary data analysis of the 2010 Gross National Happiness study of Bhutan, which was a nationwide cross sectional study with representative samples from rural and urban areas. The study included 6476 participants aged 15-98 y. The main outcome variable of interest was self-reported health status. Sleep duration was categorized as ≤ 6 h, 7 h, 8 h, 9 h, 10 h, and ≥ 11 h. Multiple logistic regressions were conducted to investigate the association between sleep duration and self-reported health status.

resultsThe mean sleep duration was 8.5 (± 1.65) h. Only 9% of the respondents slept for 7 h; 6% were short sleepers (≤ 6 h) and 84% were long sleepers (21%, 8 h; 28%, 9 h; 22%, 10 h; 13%, ≥ 11 h). We found that both short (≤ 6 h) and long sleep duration (≥ 11 h) were independently associated with poor self-reported health status.

conclusionsThis study found that people with shorter and longer sleep durations were more likely to report poorer health status.
