Risk stratification scores for hospitalization duration and disease progression in moderate and severe patients with COVID-19

Table 2. Risk categories by risk stratification scores among COVID-19 patients

	Categorization of risk			p-value
	Low	Intermediate	High	p-value
STPCAL score for hospitalization duration in moderate patients
Score	0 to 1	2 to 6	7 to 9
Patient number (%)	239 (16.9)	1122 (79.1)	57 (4.0)
Length of hospital stays, median (IQR)	8 (6, 12)	13 (8, 18)	19 (16, 25)	<0.001
Long-stay probability (%)^*	< 20.0	30.0-78.9	> 86.5
TRPNCLP score for disease progression in severely ill patients
Score	0 to 5	6 to 11	12 to 16
Patient number (%)	443 (74.7)	125 (21.1)	25 (4.2)
Progression events, No. (%)	23 (5.2)	43 (34.4)	22 (88.0)	<0.001
Progression probability (%)^*	< 12.7	18.6-69.1	> 77.9

P-values were calculated by Kruskal-Wallis H test or χ² test, and bold represents significant differences among the three subgroups. ^*, probablities correspongding to each point were calculated by logistic regression model equation. COVID-19, coronavirus disease 2019; STPCAL, symptoms, temperature, platelet count, C-reactive protein, albumin, lactate dehydrogenase; TRPNCLP, temperature, respiratory disease, platelet count, neutrophil-to-lymphocyte ratio, creatinine, lactate dehydrogenase, prothrombin time
