Perioperative Outcomes of Lung Cancer Surgery in Women: A Canadian Nationwide Retrospective Cohort Study.
Article in European journal of cardio-thoracic surgery : official journal of the European Association for Cardio-thoracic Surgery, 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
objectivesSex differences in perioperative outcomes following lung cancer surgery remain understudied. This study evaluated these differences in a national cohort.
methodsData for patients who underwent lung cancer surgery between January 2017-December 2022 at 13 hospitals were extracted from the Canadian Association of Thoracic Surgeons National Database. Preoperative characteristics, surgery-related, tumour-related, and postoperative outcomes data were collected. Mixed-effects logistic regression models were used to determine perioperative variables associated with female sex.
resultsA total of 9922 patients were included, and 55.4% were female. Female patients had higher rates of minor complications, lower rates of major complications, and lower mortality. Females were less likely to be active smokers (odds ratio [OR] = 0.66; 95% confidence interval [CI], 0.52, 0.83), have comorbidities, have squamous cell carcinoma (OR = 0.34; 95% CI, 0.26, 0.44), or an air leak complication postoperatively (OR = 0.66; 95% CI, 0.51, 0.86). However, females with chronic obstructive pulmonary disease (COPD) or squamous cell carcinoma had higher odds of experiencing an air leak complication postoperatively.
conclusionsFemales had fewer comorbidities, less advanced stage cancer, less pulmonary resection, and different tumour types, all leading to lower rates of major complications and mortality compared to males. Understanding preoperative factors that contribute to sex differences in adverse events can enhance the short- and long-term outcomes for patients with lung cancer.
