Quantitative lung CT indicators have good predictive ability for hypoxemia during one-lung ventilation in radical resection for lung cancer.

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
purposeWe aimed to identify the preoperative risk factors for hypoxemia during one-lung ventilation (OLV) in patients who underwent thoracoscopic radical resection for lung cancer and to establish a prediction model.
methodsThis retrospective study included 268 patients who underwent video-assisted thoracoscopic surgery (VATS) radical resection for lung cancer at Yunnan Cancer Hospital from October 2021 to June 2022. Logistic regression analysis was performed to identify independent preoperative risk factors for hypoxemia during OLV. A prediction model was established, and its predictive efficacy was evaluated with the consistency index (C-index) and the area under the receiver operating characteristic curve (AUC).
resultsThe multivariate analysis demonstrated that the ratio of dependent lung FLV to total lung FLV (odds ratio [OR] 0.8434; 95% confidence interval [CI] 0.7281-0.9623), dependent lung HU value (OR 0.9676; 95% CI 0.9419-0.9895), dependent lung LAV% (OR 1.1838; 95% CI 1.0856-1.3138), and DLCO% pred (OR 0.9632; 95% CI 0.9353-0.9864) were independent preoperative risk factors affecting OLV hypoxemia. The prediction model that was constructed by this indicator was internally validated, with a C-index of 0.963, an AUC of 0.96 (95% CI 0.94-0.99) for the training set, and an AUC of 0.92 (95% CI 0.83-1) for the test set.
conclusionCT-based quantitative indicators of the dependent lung are strong predictors of hypoxemia during OLV for lung cancer patients. This prediction model helps anesthesiologists to intuitively and accurately identify patients who may experience hypoxemia during OLV before surgery and develop individualized management strategies.
