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

There is a lack of data on how nighttime blood pressure (BP) might modify the relationship between sleep duration and cardiovascular disease (CVD) risk. Self-reported sleep duration data were available for 2253/2562 patients from the J-HOP Nocturnal BP study; of these, 2236 had complete follow-up data (mean age 63.0 years, 83% using antihypertensive drugs). CVD outcomes included stroke, coronary artery disease (CAD), and atherosclerotic CVD (ASCVD [stroke + CAD]). Associations between sleep duration and nighttime home BP (measured using a validated, automatic, oscillometric device) were determined. During a mean follow-up of 7.1 ± 3.8 years, there were 133 ASCVD events (52 strokes and 81 CAD events). Short sleep duration (<6 versus ≥6 and <9 h/night) was significantly associated with the risk of ASCVD (hazard ratio [HR] 1.85, 95% confidence interval [CI] 1.07-3.22), especially stroke (HR 2.47, 95% CI 1.08-5.63). When nighttime systolic BP was <120 mmHg, those with a sleep duration <6 versus ≥6 and <9 h/night had a significantly higher risk of ASCVD and CAD events (HR [95% CI] 3.46 [1.52-7.92] and 3.24 [1.21-8.69], respectively). Even patients with "optimal" sleep duration (≥6 and <9 h/night) were at significantly higher risk of stroke when nighttime systolic BP was uncontrolled (HR [95% CI] 2.76 [1.26-6.04]). Adding sleep duration and nighttime BP to a base model with standard CVD risk factors significantly improved model performance for stroke (C-statistic 0.795, 95% CI 0.737-0.856; p = 0.038). These findings highlight the importance of both optimal sleep duration and control of nocturnal hypertension for reducing the risk of CVD, especially stroke.
