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

objectivesSleep characteristics are associated with cardiovascular disease (CVD) risk and both sleep and CVD risk vary by gender. Our objective was to examine associations between polysomnographic sleep characteristics and CVD risk after excluding moderate-severe sleep apnea, and whether gender modifies these associations.

methodsThis was a cross-sectional study with at-home polysomnography in adults in Brazil (n = 1102 participants with apnea-hypopnea index (AHI) <15 events/hour). Primary exposures were N3, REM, wake after sleep onset (WASO), arousal index, and AHI, and outcomes were blood pressure (BP) and lipid levels.

resultsAssociations between sleep and BP varied by gender. In women, more N3 was associated with lower systolic BP (-0.40 mmHg per 10 minutes, 95% CI: -0.71, -0.09), lower diastolic BP (-0.29 mmHg per 10 minutes, 95% CI: -0.50, -0.07), and lower odds of hypertension (OR 0.94, 95% CI: 0.89, 0.98). In men, more WASO was associated with higher systolic BP (0.41 mmHg per 10 minutes, 95% CI: 0.08, 0.74) and higher odds of hypertension (OR 1.07, 95% CI: 1.01, 1.14). No interactions by gender were observed for lipids. More WASO was associated with lower total cholesterol (-0.71 per 10 minutes, 95% CI: -1.37, -0.05). Higher AHI was associated with higher total cholesterol (+0.97 per event/hour, 95% CI: 0.24, 1.70) and higher LDL (+0.84 per event/hour, 95% CI: 0.04, 1.64).

conclusionsN3 is more strongly associated with BP in women, which is consistent with other studies demonstrating gender differences in BP control and CVD risk and adds a novel risk factor. Longitudinal and interventional studies are required to determine whether changes in N3 result in BP changes.
