Mean and maximum absolute differences in negative log-transformed BH-adjusted P values, Jaccard similarity coefficients, and error rates (FPs and FNs) for the results of FedProt and selected meta-analysis approaches compared with centralized DEqMS results. The lowest differences are shown in bold font.
aThresholds of |log2FC| >0.5 and adjusted P value <0.05 (bacterial dataset) and |log2FC| >0.25 and adjusted P value <0.05 (human serum dataset) were used for Jaccard similarity coefficients, FPs and FNs. Metrics use each method’s own |log2FC| and BH-adjusted P values.
