Exposure–effect impact of body mass index (BMI) on invasive mechanical ventilation (IMV), severity, and hospitalized death in patients with COVID‐19. Solid line in red represents fitted linear trend and corresponding upper/lower 95% confidence interval (CI); lines with long dashes in black represent fitted non‐linear trend and corresponding upper/lower 95% CI. (A) Exposure–effect association between BMI and IMV. P nonlinearity = .018, OR = 1.43 (95% CI: 1.17–1.76) per 5 kg/m2 of BMI increment; (B) exposure–effect association between BMI and severe COVID‐19. P nonlinearity = 0.031, OR = 1.22 (95% CI: 1.13–1.31) per 5 kg/m2 of BMI increment; (C) exposure–effect association between BMI and hospitalized death. P nonlinearity = 0.0067, OR = 1.06 (95% CI: 1.03–1.09) per 5 kg/m2 of BMI increment
