Performance of DDA method on peptide quantification with match-between-run. (a) Distribution of LOD on peptide intensity stool microbiome group. The figures above each LOD group represent the number of peptides in that group, which is also displayed by the color scale. (b) R value from robust regression between log2 peptide intensity and log2 sample percentage of peptides whose LOD were at 0.5% when performing MBR. The figures above represent the number of peptides in each group. The figures on both sides represent the number (percent) of peptides whose R value larger than 0.93.
