Postoperative risks of type 2 diabetes in elderly hip fracture patients: a propensity score-matched study.
Article in Journal of bone and mineral metabolism, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
introductionType 2 diabetes is associated with an increased risk of fragility fractures, even in individuals with normal or high bone mineral density. However, the impact of type 2 diabetes on postoperative outcomes after hip fracture surgery in elderly Japanese patients remains unclear. This study evaluated the association between type 2 diabetes and postoperative complications, including in-hospital mortality, using a nationwide database in Japan. MATERIALS AND
methodsA retrospective cohort study was conducted using the Diagnosis Procedure Combination (DPC) database from April 2016 to March 2022. Patients aged ≥ 65 years who underwent hip fracture surgery were included. Propensity score matching (1:1) was performed to adjust for confounders. Logistic regression analyses were used to assess associations between type 2 diabetes and outcomes.
resultsOf the 474,293 eligible patients included in this study, 18.5% were identified as having comorbid type 2 diabetes. Following 1:1 propensity score matching, the final analytic cohorts each comprised 83,283 patients. Although statistically significant, the presence of type 2 diabetes was associated with only modest increases in the risks of postoperative myocardial infarction (risk difference [RD]: 0.0007), cognitive dysfunction (RD: 0.0029), and in-hospital mortality (RD: 0.0045), with all comparisons yielding p-values of less than 0.0001. Additionally, the length of hospital stay was longer among patients with type 2 diabetes.
conclusionsAlthough the absolute risk differences were small, type 2 diabetes remains an independent risk factor for adverse postoperative outcomes following hip fracture surgery in elderly Japanese patients. Tailored perioperative strategies may help optimize outcomes in this vulnerable population.
