Physical Resilience After Hip Fracture: Unpacking the Roles of Resistance and Recovery.
Article in Journal of the American Geriatrics Society, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundPhysical resilience-the ability to withstand, recover, or adapt after a stressor-is critical in older adults facing acute insults. We conceptualize physical resilience to comprise two distinct but related components: resistance (immediate physiological response to the stressor) and recovery (subsequent health changes). These two components were used to evaluate how individuals respond to hip fracture-a common and severe geriatric stressor.
methodsUsing data from nearly 5000 hip fracture participants, we used linear mixed-effects models to characterize a composite health status, derived from electronic health record diagnoses, 1 year before and after hip fracture. Resistance was assessed as the abrupt change in composite health status immediately after the fracture, whereas recovery represented the subsequent rate of change. We used Cox and Fine-Gray models to identify the associations of resistance and recovery with all-cause and cause-specific mortality, respectively.
findingsWe observed a significant and sharp decline in the composite health measure at the time of hip fracture. Following the fracture, the rate of health deterioration accelerated compared to the pre-fracture period. Lower resistance was associated with a 7% increase in mortality (95% CI = 1.06, 1.08); slower recovery was associated with a more than 2-fold increase in mortality (HR = 2.23, 95% CI = 2.05, 2.44). Lower resistance was associated with increased neurodegenerative mortality, whereas lower recovery was associated with increased mortality across most causes of death.
conclusionsPhysical resilience is a complex and dynamic process strongly linked to mortality outcomes post-hip fracture. Identifying individuals with lower resilience may improve clinical interventions to enhance recovery and reduce mortality.
