The joint effect of weight-adjusted waist index and physical activity on all-cause mortality in Chinese elderly patients with multimorbidity: A study based on the CLHLS from 2011 to 2018.

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.
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
backgroundThe relationship between physical activity changes, weight-adjusted waist circumference index (WWI), and mortality risk among older Chinese adults with multimorbidity remains unclear. This study aimed to examine whether changes in physical activity and WWI modify the mortality risk by analyzing data from the Chinese Longitudinal Healthy Longevity Survey (CLHLS).
methodOur study was based on the 2011 ~ 2018 wave of the CLHLS, involving a study of 2,626 older adults with multimorbidity. Cox proportional hazards models were employed to estimate hazard ratios (HRs) and 95% confidence intervals (95% CIs) and a stratified analysis was conducted to assess the combined impact of WWI and physical exercise on all-cause mortality in patients with multimorbidity.
resultPatients with multimorbidity who engaged in regular physical activity exhibited a 41% reduction in all-cause mortality compared to those who had never been physically active (HR:0.59, 95% CI:0.49, 0.70). All-cause mortality was increased by 13% in patients with high WWI and multimorbidity compared to those with low WWI (HR:1.13, 95% CI:1.01, 1.27). Furthermore, WWI-stratified analyses revealed that varying physical activity profiles had a more pronounced protective or detrimental impact on all-cause mortality among multimorbidity patients in the high WWI group compared to the low WWI group.
conclusionThis study demonstrates that both initiating and maintaining physical activity significantly reduce mortality risk in multimorbid older adults, even those with higher WWI. Our findings support integrating structured exercise interventions and routine WWI monitoring into clinical care to improve survival outcomes in this population.
