Propensity score matching analysis of the relationship between allogeneic blood transfusion and postoperative pulmonary complications in scoliosis correction surgery: 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
Background: Surgery is still the treatment of choice for patients with moderate to severe scoliosis, and vertebral column resection can significantly correct scoliosis. However, scoliosis correction surgery is associated with a high incidence of perioperative complications. We hypothesize that receiving allogeneic blood transfusions during surgery increases the risk of these complications in patients undergoing scoliosis correction surgery. Methods: This retrospective study included 512 patients who underwent scoliosis correction surgery at the Second Hospital of Zhejiang University School of Medicine between August 2016 and April 2023. Patients who experienced or did not experience transfusion were balanced in terms of baseline clinicodemographic characteristics using propensity score matching. Multivariable logistic regression of the balanced data was performed to assess the potential influence of intraoperative allogeneic transfusion on incidence of PPCs. Results: Propensity score matching led to a dataset of 322 patients, of whom 161 experienced allogeneic transfusion and 161 did not. Multifactorial logistic regression identified the following factors associated with PPCs: intraoperative allogeneic red blood cell transfusion rate (Risk Ratio (RR) 1.53 95% confidence interval (CI) 1.12-2.11, Conclusion: Intraoperative allogeneic red blood cell transfusion rate and volume during scoliosis correction surgery may be strongly associated with occurrence of PPCs.
