Comparison of the ratio of \(\mathrm{P}({t}_{i})\) distributions of target and decoy hits in various databases and in the HEK293 dataset. The blue bar shows the ratio of spectra for which \(\mathrm{P}({t}_{i})\) < 0.5 among all spectra at the 1% FDR threshold. The red bar shows the ratio of spectra for which \(\mathrm{P}({t}_{i})\) > 0.5 among all spectra at the 1% FDR threshold: a HEK293 target hits, and b HEK293 decoy hits
