Survival of hospitalized COVID-19 patients by ICU occupancy. Standardized predicted survival at 40 days after positive test by ICU occupancy. More transparent areas correspond to 95% credible intervals and less transparent ones to 50% credible intervals. Results from the model fitted to data from the second epidemic wave, including covariates ICU occupancy (modeled by restricted cubic splines with 3 knots), sex, age, comorbidity status, and the interaction between age and comorbidity status. Standardization is done by averaging predictions at 40 days for the whole population by ICU occupancy in each of the posterior samples (1000 draws)
