T146	287-670	Sentence	denotes	Risk stratification scores originally validated in patients with community acquired pneumonia (n=9) generally had higher discrimination for inhospital mortality in the validation cohort (eg, A-DROP (area under the receiver operating characteristic curve 0.74, 95% confidence interval 0.73 to 0.74) and E-CURB65 (0.76, 0.74 to 0.79)) than those developed within covid-19 cohorts (n=4:
