Evaluating the impact of Age-Adjusted Charlson Comorbidity Index on in-hospital complications in patients with femoral fracture: a retrospective cohort analysis from the MIMIC-IV 2.2 database.
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: Femoral fractures in hospitalized patients often lead to limited mobility, increasing the risk of complications like deep venous thrombosis (DVT), pressure ulcers, and delirium. These risks are particularly pronounced in elderly patients with multiple comorbidities. Monitoring such patients using reliable indices like the Age-Adjusted Charlson Comorbidity Index (ACCI) can help in early identification and management of these risks. This study investigates the association between ACCI scores and the incidence of in-hospital complications DVT, pressure ulcers, delirium in patients with femoral fractures. Methods: Using the MIMIC-IV 2.2 database, we extracted data for 4,134 patients diagnosed with femoral fractures after applying exclusion criteria such as repeated admissions, age under 18, and significant missing data. ACCI and other demographic and clinical data were used in logistic regression models and restricted cubic spline (RCS) analyses to assess the relationship between ACCI and complication risks. Results: A nonlinear association between ACCI and complication risk was identified, with significant risk increases beyond an ACCI of 5. Patients were divided into low-ACCI (≤5) and high-ACCI (>5) groups. High-ACCI patients had significantly greater risks of developing DVT (OR = 2.151), pressure ulcers (OR = 2.168), and delirium (OR = 1.791), compared to low-ACCI patients, indicating ACCI's effectiveness in predicting these complications. Conclusion: ACCI is a valuable tool for predicting the risk of in-hospital complications among femoral fracture patients, facilitating targeted interventions and improved patient management.
