^aThe survival score was calculated as follows: 0.8 × (survival AUC/maximum AUC).

^bThe weight loss score was calculated as follows: 0.2 × (weight loss AUC/maximum AUC).

^cThe total pathogenicity score was the sum of the survival and weight loss scores.

^dPathogenicity indices classify viruses as follows: most pathogenic (4) to least pathogenic (1).
