Risk factors for postoperative pulmonary complications following coronary artery bypass grafting in elderly patients: a retrospective study.

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
backgroundPostoperative pulmonary complications (PPCs) significantly impact the prognosis of elderly patients undergoing coronary artery bypass grafting (CABG), yet the risk factors for PPCs in CABG remain uncertain. The objective of this study is to identify risk factors for PPCs in elderly patients undergoing CABG.
methodsThis study retrospectively analyzed 305 elderly patients who underwent CABG at Xuanwu Hospital, from January 2019 to December 2023. The variables analyzed included patient demographics, comorbidities, anesthesia factors, surgical factors and perioperative laboratory tests. Based on the occurrence of PPCs, patients were divided into the PPC group and the none-PPC group. Univariate analysis and multivariate logistic regression analysis were employed to determine the independent risk factors of PPCs in elderly patients undergoing CABG.
resultsOf the 305 patients, 148 developed PPCs, resulting in an incidence rate of 48.5%. Compared to the none-PPCs group, patients in the PPCs group had significantly longer postoperative lengths of stay and higher perioperative mortality rates. The results indicated that NYHA classification ≥ III (P = 0.024, OR: 1.791, 95%CI: 1.080 ~ 2.972), preoperative P/F ratio (PaO
conclusionThis study identified NYHA classification ≥ III, preoperative P/F ratio < 350 mmHg and postoperative albumin levels as independent predictors of PPCs in elderly patients undergoing CABG. Further study is needed to validate these findings and explore potential interventions to mitigate the risk of PPCs in elderly CABG patients.
