The phase angle as a predictor of postoperative complications in patients undergoing lung cancer surgery.

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 phase angle (PhA), calculated by bioelectrical impedance analysis, is used as a nutritional risk indicator. A low preoperative PhA has been reported as a marker of postoperative complications in patients with cancer; however, the relationship between the PhA and postoperative complications in patients with lung cancer remains unknown. We conducted this study to assess the predictive ability of the preoperative PhA for postoperative complications in patients undergoing surgery for primary lung cancer.
methodsWe reviewed the data on 240 patients who underwent surgery for primary lung cancer at our institution between August, 2019 and August, 2021.
resultsThe PhA value in this study was 4.7 ± 0.7°. According to the Clavien-Dindo classification, grade ≥ II postoperative complications occurred in 53 patients (22.0%). Based on the multivariate logistic analysis, only the PhA (odds ratio, 0.51, 95% confidence interval, 0.29-0.90, p = 0.018) was an independent predictor of Clavien-Dindo grade ≥ II postoperative complications.
conclusionsThe PhA may be a valuable marker for predicting the risk of postoperative complications following lung cancer surgery.
