Frailty Trajectories and Determinants in Older Adults After PCI: A Longitudinal Study.
Observational study in Clinical interventions in aging, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Aim: To identify distinct frailty trajectories and their determinants in older adults during the first six months after percutaneous coronary intervention (PCI), guided by the Health Ecology Model. Design: A prospective observational design. Methods: This study investigated the frailty status of elderly patients who underwent PCI surgery at a tertiary hospital in Ningxia, China, from November 2023 to May 2024, within six months after discharge. The Latent Growth Mixture Model was utilized to identify trajectories of frailty and classify participants based on these trajectories. Then, multivariable logistic regression analysis was employed to analyze the predictive factors of different trajectories. The reporting of this study adhered to the STROBE checklist. Results: 218 elderly patients completed follow-up after PCI. There were three frailty trajectories among elderly people after PCI: the Low-Ascending Group (32.6%), the Middle-Alleviation Group (37.6%), and the High-Fluctuating Group (29.8%). Multivariate logistic regression analysis showed that depression, self-efficacy, occupation, NYHA class, and types of medication were influencing factors of their frailty trajectories ( Conclusion: The high proportion of frailty among elderly individuals after PCI should be a cause for concern. Additionally, targeted interventions based on frailty trajectories and measures like depression screening, self-efficacy support, and polypharmacy management are needed to address frailty in elderly post-PCI patients. Impact: This study highlights the importance of tracking the frailty status of elderly patients after PCI, providing a new perspective and theoretical basis for healthcare professionals to design personalized and targeted intervention plans to prevent or ameliorate frailty. Patient or Public Contribution: No patient or public contribution. The study only included patients who were research participants.
