Six proteins that qualified the three-tier criteria i.e., p-value < 0.05, FDR ≤ 0.05 and PMF score >79, are shown in bold.
*FDR determination (the probability of expected type 1 error in null hypothesis) was performed according to the method of Diz et al.9. Value ≤ 0.05 indicates that 95% findings are accurate/true.
**PMF score, for each identification, was calculated as described by Stead et al.7 using 79 as the cut-off value for positive hits.
