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

backgroundPopulation-based investigations studying the association between snoring and left ventricular hypertrophy (LVH) are lacking. Therefore, our study aims to investigate whether snoring is significantly associated with LVH, and to make clear the effect of varying degrees of snoring intensity on LVH.

methodsA total of 10,139 participants were involved in this cross-sectional study. Snoring status and snoring intensity were evaluated by a structured questionnaire. LVH was defined as left ventricular mass index ≥ 51 g/m(2.7) for both men and women.

resultsThe total prevalence of LVH was 10.0%. the prevalence increased significantly in snorers according to snoring intensity, including low (10.3%), normal (13.1%), strong (14.7%) and very strong (16.7%). After adjustment for age, race, gender, educational status, physical activity, annual income, current smoking status, current drinking status, sleep duration, hypertension, body mass index, waist circumference, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triglyceride, total cholesterol and fasting plasma glucose, snoring (OR, 1.371; 95% CI, 1.147-1.637, P < 0.001) was significantly associated with LVH. In addition, among the four kinds of intensity of snoring, normal (OR, 1.436; 95% CI, 1.126-1.832, P = 0.004), strong (OR, 1.462; 95% CI, 1.124-1.902, P < 0.001) and very strong (OR, 1.813; 95% CI, 1.273-2.684, P < 0.001), rather than low (OR, 1.094; 95% CI, 0.834-1.434, P = 0.518) were significantly associated with LVH.

conclusionsSnoring is independently associated with LVH. What's more, with the rise in snoring intensity, snoring will exert an increasing effect on LVH.
