Gender differences in outcome and use of resources do exist in Swedish intensive care, but to no advantage for women of premenopausal age

^aARDS, Acute respiratory distress syndrome; COPD, Chronic obstructive pulmonary disease. Odds ratio (OR) with 99% confidence interval (CI) and model fit (c-statistic and R ²) were calculated per diagnosis group and per age group using the main multivariate logistic regression model. See Methods section and Table 2 for details. P-values <0.05 are presented.
