Low BMI and postoperative outcomes in elderly hip fracture patients: a Japanese nationwide database study.
Article in Journal of bone and mineral metabolism, 2026. 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
introductionHip fractures are common in elderly individuals and contribute to significant morbidity and mortality. Low body mass index (BMI) is associated with osteoporosis and frailty, yet its impact on postoperative outcomes after hip fracture surgery remains unclear. MATERIALS AND
methodsWe conducted a retrospective cohort study using Japan's Diagnosis Procedure Combination (DPC) database. Patients aged ≥ 65 years undergoing surgery for hip fractures from April 2016 to March 2022 were included. Low BMI was defined as < 17.0 kg/m
resultsOf 474,293 patients identified, 63,761 matched pairs were analyzed. Compared to the non-low BMI group, the low BMI group had higher rates of urinary tract infection (3.6% vs. 3.0%; OR 1.203, 95% CI 1.131-1.280), pneumonia (5.3% vs. 3.0%; OR 1.850, 95% CI 1.746-1.961), and in-hospital mortality (3.4% vs. 1.6%; OR 2.233, 95% CI 2.068-2.411). Perioperative transfusion volume was higher in the low BMI group, while VTE was less frequent. Sensitivity analyses using < 18.5 kg/m
conclusionLow BMI is associated with increased complications and mortality following hip fracture surgery in the elderly. These findings emphasize the prognostic relevance of BMI in perioperative risk assessment.
