Models’ Predictive Accuracy Based on Different Symptoms

Symptoms	Sensitivity	Specificity	PPV	NPV	Accuracy
Fever + loss of taste + loss of smell (n = 42)	0.33	0.96	0.79	0.77	0.77
Fever + loss of smell (n = 50)	0.37	0.95	0.74	0.78	0.77
Fever + loss of taste (n = 52)	0.38	0.94	0.73	0.78	0.77
Fever + loss of taste + loss of smell + diarrhea + anorexia (n = 24)	0.21	0.99	0.88	0.75	0.76
Fever + loss of taste + loss of smell + diarrhea (n = 29)	0.25	0.98	0.86	0.76	0.76
Fever + loss of taste + loss of smell + anorexia (n = 31)	0.24	0.97	0.77	0.75	0.75

NPV, negative predictive value; PPV, positive predictive value.
