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

aimIdentifying the modifiable lifestyle-related factors associated with intrinsic capacity (IC) is essential for developing population approaches. This study examined the cross-sectional associations of nutrition-related, physical, and social factors with IC among community-dwelling older adults.

methodsParticipants were 822 community-dwelling older adults. IC was assessed across five domains of locomotion, vitality, psychological capacity, cognitive function, and sensory function. Each IC domain score was log-transformed and standardized, and a gender-specific Confirmatory factor analysis (CFA)-weighted composite IC score was constructed by fitting single-factor CFA models separately for men and women. Nutrition-related, physical, and social factors were defined according to our previous study. Participants were classified according to the quantity of lifestyle-related factors met (0-3). Multivariate linear regression analyses were performed to investigate the association between IC score with three factors comprehensively and separately on the total sample stratified by gender.

resultsThe mean age was 79.0 ± 6.6 (women, 43.3%). Compared to implementing no factors, implementing two or three factors was consistently associated with significantly higher IC scores (Unstandardized Coefficient B [95% CI], 0.49 [0.31-0.67] and 0.68 [0.47-0.89]). Implementing one factor did not reach statistical significance after full multivariable adjustment (0.17 [-0.04-0.34]). These graded associations were broadly consistent across women and men. Moreover, factor-specific analyses showed that nutrition-related, physical, and social factors were all positively associated with IC in the total sample (0.22 [0.07-0.36], 0.36 [0.20-0.52] and 0.33 [0.17-0.49]).

conclusionIn this cross-sectional study, a greater number of favorable lifestyle-related factors was positively associated with IC among community-dwelling older adults. These findings provide preliminary evidence to inform future longitudinal and intervention studies on healthy aging.
