Impact of comorbidities on preoperative and postoperative outcomes in hip fracture patients.
Article in BMC geriatrics, 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
backgroundHip fractures represent a major public health concern due to their increasing incidence in the aging population and their association with significant morbidity and mortality. Comorbidities are known to complicate both the surgical management and rehabilitation process, yet their specific impact on outcomes remains variable across studies.
objectiveThis study aimed to determine the prevalence and distribution of comorbidities in patients who presented with hip fractures and underwent surgical treatment, to evaluate perioperative and postoperative risk factors retrospectively, and to compare these findings with the existing literature.
methodsA retrospective descriptive analysis was conducted on 589 patients aged ≥ 60 years who were surgically treated for hip fractures between 2013 and 2024 at a tertiary university hospital. Demographic characteristics, surgical protocols, anesthesia types, revision rates, infection, dislocation, mobilization outcomes, hospital stay, intensive care admissions, and mortality were systematically analyzed in relation to comorbidity profiles and the number of comorbidities. Statistical analyses included chi-square, Fisher’s exact test, Mann-Whitney U, and Kruskal-Wallis tests, with p < 0.05 considered significant.
resultsHypertension (59.1%), diabetes mellitus (33.6%), coronary artery disease (21.4%), and Alzheimer’s disease (21.4%) were the most frequent comorbidities. Revision surgery was significantly associated with diabetes mellitus and congestive heart failure. Diabetes mellitus, coronary artery disease, and chronic renal failure were strong predictors of postoperative infection. While the mean hospital stay was significantly prolonged in patients with ≥ 3 comorbidities, mortality was significantly associated only with oncological diseases and chronic renal failure. Contrary to expectations, no significant association was found between overall mortality and the number of comorbidities.
conclusionComorbidities, particularly diabetes mellitus, congestive heart failure, oncological diseases, and chronic renal failure, substantially influence surgical outcomes, postoperative complications, and hospitalization in hip fracture patients. However, the number of comorbidities alone was not a predictor of mortality, highlighting the importance of the type rather than the quantity of comorbid conditions. These findings underscore the need for individualized perioperative planning and comprehensive patient counseling to reduce risks and improve postoperative outcomes.
