From: Static compliance and driving pressure are associated with ICU mortality in intubated COVID-19 ARDS
Solid lines indicate the log-odds of ICU mortality, while grey areas 95% confidence interval. A Association between static compliance of the respiratory system and intensive care unit mortality. The p value for nonlinearity was 0.01. The nonlinear effect of static compliance of the respiratory system on the intensive care unit mortality risk was modelled using restricted cubic splines. The odds ratio is presented for the interquartile ranges of the study population. B Association between driving pressure and intensive care unit mortality. Because p value for nonlinearity was 0.68, nonlinearity was not implemented in the model. The odds ratio is presented for clinically relevant range of values, according to published data [5, 6]. C Association between tidal volume and intensive care unit mortality. Because p value for nonlinearity was 0.20, nonlinearity was not implemented in the model. The odds ratio is presented for clinically relevant range of values, according to literature data [2, 4].
