Figure 2

Boxplot of non-parametric differences between 3-HPMA measured in all samples using 3-HPMA-d 3 and 3-HPMA-13C 3 -15N internal standards. The hypothesis (Ho) is based on no difference (0) between the 3-HPMA-d3 measures minus the 3-HPMA-13C3-15N measures. The box plot shows a clear positive difference with p = 0 based on a Wilcoxon paired t-test with a 95% confidence interval for the mean difference (x).
