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

backgroundCardiovascular diseases (CVDs) are a major global health issue, influenced by income level and sleep duration.

objectivesThis study sought to assess the impact of income inequality and sleep duration on CVD outcomes in China and the United Kingdom.

methodsWe analyzed data from the China Kadoorie Biobank (CKB) (n = 486,131) and UK Biobank (UKB) (n = 403,858). Income level was categorized into low, medium, and high based on the annual household income, and sleep duration into short (<7 hours), optimal (7-9 hours), and long (>9 hours). Cox models estimated HRs for income level, sleep duration, and CVD outcomes.

resultsA total of 134,227 incident CVD cases and 16,852 deaths were identified. Low income was associated with higher CVD incidence and mortality in both cohorts (P < 0.001). Short and long sleep durations increased CVD incidence in both cohorts (P < 0.05), except for long sleep and ischemic heart disease in the CKB. Long sleep duration was associated with higher CVD mortality in both cohorts, whereas short sleep duration increased ischemic heart disease risk in the UKB. Compared with individuals of high income and optimal sleep duration, low income was associated with higher CVD risk across all sleep categories. Medium income raised CVD incidence risk in all sleep categories, with mortality associations varying by sleep duration between the CKB and the UKB.

conclusionsIncome level and sleep duration independently and jointly affect CVD incidence and mortality. Low income and suboptimal sleep duration are detrimental to cardiovascular health, highlighting the need for public health strategies to address income disparities and promote optimal sleep for CVD prevention.
