Case fatality for each Ps category (Case fatality = the number of deaths divided by the number of patients x 100 for each Pscategory). The lowest Ps category (0-0.1) and the highest Ps category (0.9-1.0) had the highest fatality 93.3% and the lowestfatality 1.5%, respectively. The trend that the fatality would decrease as Ps increased was observed. Cases without outcomewere excluded from this analysis.n/a: not assessed due to missing values.
