  1. a Test set 1: leave-one-out cross-validation test
  2. b Test set 2: independent literature-based test
  3. c Test set 3: SILAC experimental independent test
  4. d These sensitivity measures represent average sensitivity values over ten runs. Their standard deviations were all below 0.03.
  5. e PPV: positive predictive value. These measures represent average PPV values over ten runs. Their standard deviations were all below 0.1.
