Association of intraoperative end-tidal CO₂ levels with postoperative pulmonary complications in thoracoscopic lobectomy: a retrospective cohort study.
Observational study in BMC anesthesiology, 2026. 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
backgroundLung-protective ventilation strategies (LPVS) are widely used to reduce postoperative pulmonary complications (PPCs) in patients undergoing one-lung ventilation. The relationship between the partial pressure of carbon dioxide in end-expiratory gas (P
methodsThis retrospective, observational, single-centre study included patients who underwent thoracoscopic lung lobectomy with LPVS between 31 December 2020 and 31 December 2024. The primary outcome was the incidence of PPCs during hospitalisation; the secondary outcome was postoperative length of stay. General and intraoperative characteristics were compared between patients who developed and those who did not develop PPCs. Multivariable logistic regression was performed to determine independent risk factor of PPCs. Subsequently, a predictive nomogram for PPC events was developed in R. The performance of nomogram model was comprehensively evaluated through ROC curve, calibration plot, and the Hosmer-Lemeshow goodness-of-fit test.
resultsAmong the 383 patients included, 74 (19.3%) developed PPCs. The PPCs group had significantly lower P
conclusionsThe incidence of PPCs in patients undergoing thoracoscopic lung lobectomy with LPVS was 19.3%. P
