The position is numbered using the corresponding residue number in the H5 HA sequence or the corresponding one in the H3 HA protein;
The position in H1 was based on the amino acid number in HA of PR8 (PDB ID 1RU7);
The mutations are predicted to affect the titers in immunologic datasets, and the corresponding antibody binding sites in H3 HA are shown in parentheses. RBS denotes receptor-binding site;
The weight was an mean of absolute weight values calculated from a total of 100 runs using HI or MN data, and the numbers in the parenthesis denote the corresponding standard deviations;
The bootstrap values were calculated based on 100 runs.
