Development and validation of a predictive model for postoperative pulmonary complications after colorectal cancer surgery: a retrospective study.
Article in World journal of surgical oncology, 2025. 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
backgroundPostoperative pulmonary complications (PPCs) significantly impact patient outcomes after colorectal cancer (CRC) surgery. Studies on PPCs associated with CRC remain limited. This study was designed to create and verify a risk prediction model through the identification of factors associated with a higher risk of PPCs after CRC surgery.
methodsPatients who underwent CRC surgery at Fujian Medical University Union Hospital from September 2019 through September 2021 were included in this study. They were divided into training and validation groups and categorized into the PPC group and non-PPC group. We used multivariable logistic regression analysis to determine independent predictors of PPCs. A nomogram was constructed using the identified risk factors and later validated via receiver operating characteristic (ROC) curves, calibration curves, and decision curve analysis to assess its predictive performance.
resultsA total of 1861 patients were enrolled and allocated to training and testing sets at an 80:20 ratio. The analyzed results revealed that surgical site, surgical approach, duration of surgery, age, perioperative blood transfusion, asthma, and fasting plasma glucose were risk factors for PPCs in patients with CRC. The receiver operating characteristic curve areas under the curve (AUCs) for the training and validation sets were 0.734 and 0.732, respectively. We found that the model calibration curve showed favorable consistency, whereas decision curve analysis (DCA) revealed a substantial expected net benefit.
conclusionsThe model demonstrates high predictive accuracy and efficiency for PPCs in patients undergoing CRC surgery.
