Prevalence and lifestyle factors associated with sarcopenic obesity among older adults with central obesity: A cross-sectional study using 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
With population aging and lifestyle changes, sarcopenic obesity (SO) - the coexistence of sarcopenia and obesity - has become a growing health concern in older adults. This study aimed to estimate the prevalence of SO among older adults with central obesity and to identify associated factors, particularly those related to lifestyle. Of the 4250 centrally obese participants, 806 met the criteria for SO, corresponding to a prevalence of 19.0%. After adjustment, SO was independently associated with older age (odds ratio [OR] = 1.138, P < .001), female sex (OR = 2.638, P < .001), and rural residence (OR = 1.776, P = .02). Lifestyle-related factors included eating fewer than 3 meals per day (OR = 1.823, P =.005) and nonoptimal sleep duration (<6 hours: OR = 1.585, P =.007; >8 hours: OR = 1.702, P =.05, marginally significant). In contrast, light-intensity physical activity was associated with lower odds of SO (OR = 0.601, P =.03). In conclusion, maintaining regular 3-meal dietary patterns, engaging in light-intensity physical activity such as walking or leisurely strolling, and having adequate sleep duration (6-8 hours) were associated with a lower prevalence. Prospective studies are warranted to confirm causality.
