Proteomic screening of urine collected post-HSCT. The days post-HSCT (x axis) are plotted against the classification factor (CF) (y axis) as described (Weissinger et al., 2007b). The cutoff for diagnosis of acute GvHD was set to CFâ=â+0.2 and is indicated as a dotted line. Proteomic screening data were obtained from five of nine patients, and four examples are shown here (UPN 1040, 1048, 1159, and 1208).
