Individual and combined effects of somatic and mental disorders on reoperation risk after hip fracture surgery: a nationwide danish cohort study of 110,625 patients.

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
purposeSurgical complications after hip fracture surgery are common, particularly among patients with comorbidities. We examined the risk of reoperation concerning individual comorbidity groups, their combinations, and overall comorbidity burden.
methodsUsing nationwide Danish registry data, we identified all patients undergoing hip fracture surgery between 2004 and 2021. Comorbidities were analysed as: (1) 10 major comorbidity groups, (2) all pairwise combinations of the 10 groups, and (3) overall comorbidity burden based on the 10 groups. Reoperation risk was estimated with 95% confidence intervals (CI), treating death as a competing event.
resultsWe included 110,625 patients, with a mean age of 82.4 years (70% female). The most prevalent comorbidity groups were cardiovascular (54%), renal/haematological (24%), and metabolic (20%) disorders. The highest 30-day reoperation risks were observed in patients with mental disorders 4.8% (CI 4.3-5.3) and musculoskeletal disorders 4.7% (CI 4.2-5.3). Compared with patients without comorbidities, adjusted hazard ratios (aHRs) for reoperation were 1.53 (CI 1.27-1.83) for neurological/alcohol disorders and 1.40 (CI 1.15-1.70) for mental disorders. Several combinations were associated with a significantly increased reoperation risk, highest for mental and hepatic/gastrointestinal disorders, with an aHR of 2.27 (CI 1.20-4.32). The reoperation risk increased with comorbidity burden, reaching an aHR of 1.33 (CI 1.11-1.59) for patients with ≥ 5 comorbidities. Similar patterns were seen at 365 days.
conclusionSpecific comorbidities, particularly mental, hepatic/gastrointestinal, neurological/alcohol, and musculoskeletal disorders, were associated with increased reoperation risk after hip fracture surgery. Risk was highest for certain comorbidity combinations, highlighting the prognostic value of comorbidity profiles beyond overall burden and supporting their use in stratified care.
