⁺Standard error computation for individual R_ivalues is based on derivation given in reference 11; *Sites found with model A but not with model B; ^sites found with model B, but not with model A; ~ Number of sites with differences in R_ivalues exceeding threshold Z scores; ^@Number of sites with differences in R_ivalues less than threshold.
