Social frailty independently predicts 9-year mortality among community-dwelling older adults in Mexico: validation of a brief social frailty index.
Article in Frontiers in public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Introduction: Social frailty, defined as deficits in social resources, roles, and engagement, is an emerging risk dimension. However, evidence on its measurement and prognostic value in Latin America is limited. Methods: Using nationally representative data from the Mexican Health and Aging Study (2012-2021), we adapted a five-item Social Frailty Index (SFI) and evaluated its psychometric properties and association with 9-year all-cause mortality in 5,400 community-dwelling adults aged ≥60 years. Results: At baseline, 38.9% were pre-frail (SFI = 1) and 25.2% were frail (SFI ≥ 2). Mortality increased progressively across categories. In fully adjusted Cox models, pre-frailty (HR = 1.21, 95%CI: 1.06-1.37) and frailty (HR = 1.56, 95%CI: 1.36-1.79) independently predicted higher mortality risk. Discussion: The SFI, adapted to available MHAS data, demonstrated prognostic relevance. This provides initial evidence supporting further research on social frailty assessment in the region, including cultural adaptation and external validation.
