B: Hypoxic fraction in lung metastatic nodules. Pimonidazole adduct immunoreactivity was automatically quantified and expressed as fractional positive areas per nodule (rightmost panel). F(5,110) = 7.544 and P< 0.0001 for overall treatment by Brown-Forsythe ANOVA; *, P< 0.01 vs vehicle; #, P= 0.0111 doublet LDM cyclophosphamide + capecitabine vs LDM cyclophosphamide + MTD capecitabine by Benjamini, Krieger and Yekuteli post hoc test.
