Determinants of hospital length of stay in older adults after hip fracture: a prospective cohort study.
Observational study 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
objectivesTo investigate factors associated with hospitalization length in older adults after hip fracture surgery.
designProspective observational cohort study. A total of 172 older adults (mean age 79.01 ± 8.66 years; 70.30% women) hospitalized for fragility hip fractures. Data were collected within the first 24 hours post-surgery. PRIMARY OUTCOME MEASURES: Hospitalization length (in days). Factors investigated for the association with length of stay included sociodemographic, surgical, and laboratory variables, as well as multimorbidity, polypharmacy, self report of pain, cognitive, emotional, nutritional, and functional status. A generalized linear model adjusted for age and sex was used, with a significance level of 5% (p ≤ 0.05).
resultsThe mean hospitalization length was 5.4 days. Cognitive impairment was observed in 86.9% of participants, depressive symptoms in 63.6%, and 68.8% were at risk of malnutrition. Mean handgrip strength was 18.48 kg. Generalized linear model analysis indicated that a longer interval (in days) from fracture to surgery, delayed surgery, higher ferritin and urea levels, lower Cumulated Ambulation Score (CAS). and lower handgrip strength were associated with longer hospitalization (p < 0.05).
conclusionsA longer fracture-to-surgery interval (including delayed surgery), higher urea and ferritin levels, and poorer early functional status (lower CAS and reduced handgrip strength) were independently associated with a longer hospital stay among older adults with hip fracture. These findings support hospital strategies to minimize surgical delays, monitor renal-related and inflammatory markers, and incorporate early functional assessments to identify patients at risk of prolonged hospitalization. Addressing system-level contributors to surgical delay (e.g., access barriers, transportation, bed availability) may also improve the continuum of care.
