  1. Data are given as medians and the interquartile ranges (iqr) for the concentrations in pM. The sample sizes for the samples taken during the morning and afternoon, respectively, were: control, 15 and 12; NP, 17 and 17; CWP 5 and 9. P values from two-way robust Wilcoxon analyses [22, 23] show main effects of condition (“C”), sampling time (“T”) and the interaction C × T. P values <0.05 are shown in bold text
