PRISMA checklist and flow chart

This dataset accompanies a systematic review and meta-analysis conducted according to the PRISMA 2020 guidelines. The study evaluates the incidence and perioperative risk factors associated with postoperative infectious pneumonia (PIP) among adult patients undergoing cardiothoracic procedures, including coronary artery bypass grafting (CABG), heart valve surgery, and thoracic oncologic surgeries. The final analysis includes six high-quality cohort studies published between January 2021 and December 2023, totaling 4,392 patients.<br>The repository contains the following materials:<br>PRISMA 2020 Checklist: A completed checklist to ensure compliance with standardized reporting guidelines.<br>PRISMA 2020 Flow Diagram: A visual representation of the study selection process.<br>Extracted Data Spreadsheet: Includes study identifiers, sample size, incidence rates of PIP, odds ratios, and confidence intervals for key risk factors.<br>Search Strategy: Detailed Boolean strings and sources used for literature search (PubMed, Embase, Scopus, ClinicalTrials.gov, WHO ICTRP).<br>PROSPERO Registration Record: The protocol was registered under PROSPERO 2025 CRD420251057914.
