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

Background Elevated long-term systolic blood pressure and resting heart rate (RHR) variability are suggested to amplify the risk of all-cause mortality (ACM). However, the link between increased RHR and pulse pressure for ACM remained unclear. Methods and Results This study analyzed 46 751 individuals from Kailuan Cohort Study for the end outcome of ACM. A Cox regression model was used to estimate hazard ratios for death events. Kaplan-Meier analysis was performed to study the differences in survival as stratified by the SD, coefficient of variation, and average real variability of RHR and pulse pressure quartiles. A total of 1667 deaths (<65 years of age=866/40351, ≥65 years of age=801/6400) were recorded over 4.97±0.69 years follow-up. Participants under the age of 65 years in the third and fourth quartiles of pulse pressure SD had an independent increase in risk for ACM (hazard ratio [95% CI], 1.16 [1.06-1.28]; and 1.19 [1.05-1.35], respectively). Additionally, participants >65 years of age had a higher risk for ACM across quartiles of RHR-SD. The hazard ratio (95% CI) for the subjects in quartiles 2, 3, and 4 were 1.81 (1.10-2.97), 2.31 (1.37-1.3.90), and 2.64 (1.63-4.29), respectively. Conclusions An elevated long-term RHR variability combined with an increased pulse pressure variability or vice versa amplifies the risk of ACM.
