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

objectiveTo explore the prospective association between physical activity level and mortality risk in Chinese adults with chronic obstructive pulmonary disease (COPD).

methodsBased on the China Kadoorie Biobank (CKB) who had COPD at the baseline survey, this study employed the Cox proportional hazards regression model to estimate the prospective associations between the overall physical activity, different intensities (low-level, moderate-to-vigorous-level), and types (occupational, non-occupational) of physical activity level and the risks of all-cause and cause-specific mortality, such as vascular diseases, cancer, and respiratory diseases. Based on the quintiles of physical activity level, participants were divided into five groups (Q1-Q5), with the lowest quintile group (Q1) as the reference group. Hazard ratio (

resultsAmong 33 588 COPD patients at the baseline survey, 8 314 (22.2%) deaths were documented during an average follow-up of (11.1±3.1) years. Negative linear associations between the overall physical activity level and mortality risk from all-cause, vascular, and respiratory diseases were observed (

conclusionPhysical activity could reduce the mortality risk in a dose-response relationship among COPD patients, regardless of its intensity and type, especially among individuals aged 60 and above, females, and those with poor self-report health status.
