“…In comparison to individuals of normal weight, the corrected odds ratios for severely obese, obese, and overweight patients were 1.57 (95% CI: 1.14–2.17), 1.55(1.19–2.02), and 1.31 (1.05–1.62), respectively [19] . The number of patients requiring IMV rose with BMI groups in retrospective French cohort report (chi-square test for trend, p<0.01), and it was highest in subjects (85.7%) with BMI greater than 35 kg/m 2 [20] . Liberated from hypertension, diabetes, and age, the requirement for IMV was strongly linked with BMI (p<0.05) and male sex (p<0.05) in multivariate logistic regression.…”
