B Mortality by Hp time limit. C Distribution of patients according to the time spent above the CFH and below the Hp limit, colored by ICU mortality. D Prediction of ICU mortality based on the time spent above the CFH and below the Hp limits. Dashed lines represent the calculated time limits for CFH (13.3%) and Hp (18.2%)Back to article page
