Results of LME models with shift parameter 0: P-value of F-test on the slope parameters, AIC, ratios between the standard deviation of the random effect and the fixed effect of the intercept and the slope.

All models have been developed using the same number of observations (649) grouped by patients. The AIC can be used to compare models with the same dependent variable. AIC: Akaike Information Criterion; LME: Linear Multiple-Effect; SOFA: daily Sequential Organ Failure Assessment; CPIS: Clinical Pulmonary Infection Score.
