  1. Mean Δ EF and standard deviation for the MCS and MCS ext similarity methods at 1%, 5% and 10% of the database (ZINC subset). The extension fingerprint is calculated from 10% of the ligands (approach B2). Improvements of MCS ext compared to MCS are marked in bold print. CAC = ChEMBL activity class. w/d/l = wins/draws/losses.
