Association of acute kidney injury stages with in-hospital and long-term mortality in older adults with hip fractures.
Article in Annals of medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundHip fractures and acute kidney injury (AKI) are common among older adults and are each associated with increased morbidity and mortality. We aimed to evaluate whether AKI severity is associated with increased mortality and institutionalization in older adult patients with hip fractures.
methodsThis single-centre, retrospective study included patients aged ≥65 years who underwent surgery for hip fractures. Those with stage 4 or 5 chronic kidney disease or end-stage kidney disease were excluded. AKI was defined and categorized according to the Kidney Disease: Improving Global Outcomes guideline. Patients who did not develop AKI served as the reference group for subsequent analyses.
resultsOverall, 661 older adults with hip fractures were included (median age: 82.0 [76.0-86.0] years, women: 76.3%). Among these, 35.9% had AKI, with 80.2, 11.8, and 8.0% classified as stages 1, 2, and 3, respectively. Thirteen patients died during hospitalization. During a median follow-up period of 4.3 (2.6-5.9) years, 301 patients died. Stage 3 AKI was associated with in-hospital mortality compared to patients without AKI (HR, 7.82 [1.21-50.72],
conclusionsHigher AKI stages are associated with increased in-hospital and long-term mortality in older adults with hip fractures. Preventing AKI development and progression is essential to improve prognosis in this vulnerable population.
