Risk factors for death or serious adverse events within 3-month after surgery in frail older persons with hip fractures and development and validation of a risk prediction model: Based on LASSO-logistic regression.
Observational study in BMC geriatrics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundThe number of frail older persons with hip fractures significantly increases. Some research indicated the incidence of mortality and adverse events for frail patients is higher than for non-frail patients. This article explores the incidence, development, and validation of a predictive model of serious adverse events and mortality in the 3-month following period.
methodsThis was an observational cohort study conducted at a tertiary hospital. Participants were consecutively admitted from December 2022 to August 2024. A total of 145 participants were included in this study. The LASSO regression and Cox proportional hazards regression analysis were developed to predict the model. Receiver operating characteristic (ROC) curves, Area under the curve (AUC), and C-index were used to assess model performance.
results26 (17.93%) patients have died or experienced serious adverse events after surgery in the 3-month follow up. The Cox proportional hazards regression analysis indicates age and the number of drugs for postoperative treatment are risk factors. Hemoglobin at admission and a high Barthel index of activities of daily living (before fracture two weeks) are protective factors. The model achieved a high AUC of 0.837 and a C-index of 0.772 (95% CI: 0.690-0.853). The sensitivity is 0.842 and the specificity is 0.675 which suggests great discrimination. The Hosmer-Lemeshow goodness-of-fit test shows X
conclusionsThis study indicates a high incidence of death or serious adverse events within 3-month after surgery in frail older persons with hip fractures. Age, the number of drugs for postoperative treatment, hemoglobin at admission, and Barthel index of activities of daily living (before fracture two weeks) are predictors. The nomogram helps healthcare to screen patients with high risk and to provide references for perioperative management and discharge care.
