Multivariable analysis of factors associated with impaired “physical” health-related quality-of-life scale (SF-36 PCS) and “mental” health-related quality-of-life scale (SF-36 MCS) in C-ARDS survivors. The figure shows factors associated with SF-36 physical component summary score (PCS) and SF-36 mental component summary score (MCS) < 40 (dependent variable), the calculated adjusted odds ratios, and the 95% confidence intervals, based on the logistic regression, on the x-axis, and on the correspondent forest plot. In red, variables significantly associated with an impaired quality of life. Reference values for the dependent variable: PCS and MCS ≥ 40. Covariate values are on the y-axis, with reference values, when applicable (factors). Variables were transformed as follows: PaO₂ to FiO₂/100, ventilation (days)/10, hospital LOS (days)/10; ventilation (days): duration of ventilation with PEEP > 5 cmH₂0; LOS: length of stay
