Grip strength-to-weight ratio, all-cause and cardiovascular mortality, and cardiovascular disease prevalence: Evidence from NHANES and CHARLS.

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
Objective: The study aimed to investigate the relationships between grip strength-to-weight ratio (GSWR) and all-cause mortality, cardiovascular mortality, and prevalence of cardiovascular disease (CVD). Methods: Data were analyzed from two nationally representative cohorts: the National Health and Nutrition Examination Survey (NHANES) and the China Health and Retirement Longitudinal Study (CHARLS). Weighted Cox proportional hazards models were used to estimate hazard ratios (HRs) for mortality outcomes, while weighted logistic regression evaluated the association between GSWR and CVD prevalence. Multivariable-adjusted restricted cubic splines (RCS) were used to examine potential non-linear relationships. Results: Over median follow-up of 82.19 months and 100.07 months, individuals in the highest GSWR quartile exhibited a 73 % reduction in all-cause mortality (HR: 0.27, 95 % CI: 0.16-0.43) in American adults, and a 47 % reduction (HR: 0.53, 95 % CI: 0.43-0.65) in Chinese middle-aged and elderly populations, compared to those in the lowest quartile. After a median follow-up of 83.66 months, cardiovascular mortality was reduced by 69 % (HR: 0.31, 95 % CI: 0.22-0.44), 69 % (HR: 0.31, 95 % CI: 0.16-0.59), and 79 % (HR: 0.21, 95 % CI: 0.09-0.48) for each increase in GSWR quartile among American adults. An typical l-shaped non-linear relationship was observed between GSWR and both all-cause and cardiovascular mortality, with a similar non-linear association identified for CVD prevalence. Conclusion: The GSWR was non-linearly associated with all-cause mortality, cardiovascular mortality, and prevalence of CVD. It can serve as a valuable health index, encouraging strength training among middle-aged and elderly individuals to maintain and enhance functional abilities.
