ERVW-1 and infection: Consistent with comparable median ADCC titers for 1086.c and 1157ipd3N4 Env, 1157ipd3N4 Env-specific ADCC titers trended toward a negative correlation with the number of challenges required for infection, although this trend was not substantiated after adjusting for FDR (Table 2; r = −0.568, unadjusted P = 0.0580, and FDR-adjusted P = 0.4548).
