Surveillance of postoperative respiratory complications in Japanese patients with hip fractures using ARISCAT score.
Article in Musculoskeletal surgery, 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
purposeThe ARISCAT score can reportedly be used to detect perioperative respiratory complications when they are not predictable by routine pulmonary function tests, blood gas tests, or chest radiography. However, its validity in Japanese patients with hip fractures is unverified. Here, we aim to determine the sensitivity and specificity of the ARISCAT score for the prevalence of respiratory complications in Japanese patients with hip fractures.
methodsThis study retrospective cohort analysis included patients that underwent surgery for hip fracture at our hospital between July 2020 and March 2022. The primary outcome was the rate of postoperative respiratory issues (pneumothorax, aspiration pneumonia, respiratory infection, bronchospasm, respiratory failure, atelectasis, and pleural effusion).
resultsRespiratory complications occurred in 17 of 389 patients with hip fractures, with an incidence rate [95% CI] of 4.4% (2.3, 6.4). The mean age was 83.7 [8.7] years, 27.8% were men, and 232 of them (59.6%) had femoral neck fractures. The discriminative power of the ARISCAT score model for the occurrence of respiratory complications was C-statistic 0.71 [0.57,0.83]. Sensitivity and specificity were 52.9% [29.2, 76.7] and 76.8% [72.6, 81.2], respectively, for a score of ≥ 26, and 42.9% [6.2, 79.5] and 96.5% [94.6, 98.4], respectively, for a score of ≥ 45.
conclusionThe ARISCAT score had low sensitivity for detecting respiratory complications in Japanese patients with hip fractures. Surveillance of postoperative respiratory complications in Japan should be via regionally validated tools.
