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

backgroundNon-neoplastic digestive system diseases (NNDSD) are highly prevalent among middle-aged and older adults and represent a substantial global health burden. Dynapenic abdominal obesity (DAO), a clinical phenotype characterized by low muscle strength (dynapenia) combined with abdominal obesity, has been associated with a range of chronic diseases. However, the prospective association between DAO and incident NNDSD has not yet been elucidated. This study aimed to examine the prospective association between DAO and the risk of new-onset NNDSD.

methodsA total of 5,956 participants from five waves of the China Health and Retirement Longitudinal Study were included in the present analysis. Participants were classified into four groups: non-dynapenic/non-abdominally obese (ND/NAO), abdominal obesity only (ND/AO), dynapenia only (D/NAO), and DAO. Multivariable Cox proportional hazards models were employed to evaluate the association between DAO and incident NNDSD.

resultsDuring a median 9-year follow-up, 1,082 incident cases of NNDSD were identified. In the overall population, participants with DAO exhibited a significantly higher risk of NNDSD than those in the ND/NAO group (HR = 1.597, 95% CI: 1.121-2.276). Notably, a pronounced sex-specific difference was observed. A significant association was observed among women (HR = 1.820, 95% CI: 1.235-2.683), whereas no significant association was identified among men.

conclusionThe coexistence of dynapenia and abdominal obesity was associated with an increased risk of incident NNDSD among middle-aged and older women, whereas no such association was observed among men. Early identification of the DAO phenotype may facilitate the implementation of targeted preventive interventions, including combined resistance and aerobic exercise programs, to reduce the risk of NNDSD.
