Prediction of Postoperative Pulmonary Complications in Geriatric Patients with Hip Fracture Using Lung Ultrasonography Score and Diaphragmatic Mobility.
Observational study in Clinical interventions in aging, 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
Purpose: Postoperative pulmonary complications (PPCs), common in geriatric patients with hip fractures, are associated with increased morbidity and mortality rates. Bedside ultrasonography may improve perioperative pulmonary risk stratification. This study aimed to evaluate the predictive value of the lung ultrasonography score (LUS) and diaphragmatic mobility (DM) for PPCs and identify the optimal index. Patients and Methods: This prospective observational study included 192 geriatric patients with hip fractures who underwent surgery. One day preoperatively, LUS and DM were assessed at bedside. All patients received general anesthesia combined with a regional block and were followed up for 30 days postoperatively for the occurrence of PPCs. Receiver operating characteristic (ROC) curve analysis and multivariate logistic regression were used to evaluate predictive performance and adjust for confounders. Results: PPCs occurred in 28.64% (55/192) of the patients. LUS and DM exhibited moderate predictive efficacies for PPCs (LUS: AUC = 0.740, 95% CI: 0.653-0.826; DM: AUC = 0.733, 95% CI: 0.655-0.812). At a cutoff value of LUS > 5 cm, the negative predictive value reached 81.9%, and at a cutoff value of DM < 3.7 cm, the negative predictive value reached 87.6%. After multivariable adjustment, a LUS> 5 and DM < 3.7 cm remained independent predictors of PPCs (LUS > 5: adjusted OR = 6.363, 95% CI: 2.609-15.515; P < 0.001; DM < 3.7 cm: adjusted OR = 5.011, 95% CI: 2.106-11.923; P < 0.001). Integration of LUS (LUS > 5) and DM (DM < 3.7 cm) with ARISCAT significantly improved predictive performance (AUC = 0.851 with the integrated model vs. 0.684 with ARISCAT alone; DeLong's P < 0.001). Conclusion: LUS and DM effectively predicted PPCs in geriatric patients with hip fractures. The integration of LUS and DM with ARISCAT markedly enhances predictive accuracy, suggesting that lung and diaphragmatic ultrasound may serve as useful bedside tools for perioperative respiratory risk assessment.
