Table 3.
Example patient data: in the first column, we present a list of variables used in the ML model; in the second column, we present the raw value for that variable, with NaN indicating missing data for that patient; in the third column, we present the continuous age-normalized score. Variables marked with an asterisk are not converted to deviance scores as they are equally informative for children and adults and are simply normalized at the time of training. Variables that have been bolded were transformed using the continuous SOFA transformations.
