Figure 1.
Distribution of ICU LoS for survivors and non-survivors.
Table 1.
Demographics of ICU admissions included in the analysis, for ICU survivors and ICU non-survivors separately (n = 32,667).
Table 2.
Estimated performance of regression models, when using all patients for model construction and model validation, but no cyclical terms.
Table 3.
Observed and predicted ICU LoS (median (IQR)), for ICU survivors and ICU non-survivors.
Table 4.
Estimated performance of regression models, when constructing models using ICU survivors and ICU non-survivors separately, but no cyclical terms.
Table 5.
Estimated performance of regression models, when constructing models using all patients and cyclical terms.
Table 6.
Performance measures using all patients for model prediction, but not including cyclical terms as covariate separated, for patients with length of stay smaller than the 75% percentile and larger or equal than the 75% percentile for validation.
