Associations of transitions in frailty and depressive symptoms with the risk of cardiovascular disease in adults with hypertension: findings from three aging cohorts.

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
objectivesTo examine the relationships of baseline status and changes in frailty and depressive symptoms with cardiovascular disease (CVD) among older adults with hypertension.
designMultinational prospective cohort study harmonizing data from three aging cohorts (CHARLS, HRS, MHAS).
settingCommunity-based surveys conducted in China (2011-2020), the United States (2012-2020), and Mexico (2012-2021).
participantsA total of 12,230 older adults with hypertension, aged ≥50 years, who were free of CVD at baseline and had at least two assessments of frailty and depressive symptoms.
interventionNone. MEASUREMENTS: Frailty was evaluated by the frailty index (FI) and depressive symptoms were evaluated using validated scales. Both were measured at baseline and at a follow-up visit approximately two years later. The primary outcome was incident CVD, including heart disease or stroke. Cox proportional hazards models were used to estimate hazard ratio (HR) with 95% confidence interval (CI). Mediation analysis, joint analysis, and multiple sensitivity analyses were performed.
resultsDuring a median follow-up of 8 years, 2,996 participants developed CVD. Baseline frailty (HR = 1.39, 95% CI: 1.25-1.53) and depressive symptoms (HR = 1.18, 95% CI: 1.09-1.28) were related to elevated risks for CVD. Progression from non-frailty to frailty was associated with a 53% increase in CVD risk (95% CI: 1.37-1.72), while remission to non-frailty was linked to a 30% lower risk (95% CI: 0.58-0.85). Similarly, progression to depressive status was associated with higher risk (HR = 1.27, 95% CI: 1.12-1.43), whereas reversion showed a lower risk (HR = 0.82, 95% CI: 0.73-0.92). Depressive symptoms accounted for 10.12% of the association between frailty and incident CVD.
conclusionProgression of frailty and depressive symptoms was related to increased risk of CVD, while recovery was associated with protective effects. These findings suggest the potential relevance of serial monitoring of both physical and psychological status among older adults with hypertension. Public health strategies that prioritize targeted screening and interventions for frailty and depressive symptoms might reduce the risk of CVD.
