Association between frailty index and all-cause mortality in hospitalized elderly patients with osteoporotic fractures: a retrospective cohort study.
Article in Frontiers in medicine, 2025. 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
Background: Osteoporotic fractures (OPF) represent a significant health concern among the elderly population. Frailty, a prevalent condition in this demographic, can be evaluated via the Frailty Index (FI). This study investigated the association between FI and all-cause mortality (ACM) in aged individuals with osteoporosis (OP). Methods: This retrospective cohort study included 19,332 patients who underwent surgical treatment for fractures at Kunshan First People's Hospital between January 1, 2017, and August 31, 2023. Among these, 4,782 patients aged ≥ 50 years were diagnosed with OPF. The FI was developed based on 30 health indicators, and it requires the availability of at least 75% of the variables for all patients. Moreover, ACM was monitored from the time of hospitalization until death or the end of the study period. Data on the correlation between FI and ACM were statistically evaluated, including the Cox proportional hazard regression model, interaction test, smooth curve fitting, K-M survival curve, threshold effect, subgroup, and sensitivity analyses. Results: Among the 3,833 patients, the mean age was 68.77 years, with an average FI of 0.07. A substantial positive correlation was observed between FI and ACM (HR = 1.05, 95% CI: 1.03-1.07, Conclusion: This study establishes a significant correlation between the FI and ACM in elderly patients with OPF, underscoring the importance of frailty measurement in clinical management. These findings support the need for targeted interventions to improve outcomes in this high-risk population and emphasize the necessity of further research to develop effective screening and management strategies.
