^*The odds ratio and 95% confidence intervals (CI) for each variable were calculated after multivariable adjustment for age, sex, Acute Physiology and Chronic Health Evaluation II score, admission type, PaO₂/FiO₂ ratio and ventilatory ratio on admission, prone positioning and neuromuscular blocking agent treatments within 24 h
