  1. SENFAMO, sensitivity of model with FAMO; SENcontrol, sensitivity of control model; SPECFAMO, specificity of model with FAMO; SPECcontrol, specificity of control model; P value, the probability to obtain a result as extreme as that in the hypothesis test which assumed that FAMO performance was worse than the control model.
