Table 4 Main descriptors of the distribution of concentrations (µmol L−1) in plasma samples collected from the control group (N = 19) and newborns enrolled in the HYPOTOP trial 48 h after the administration of the first dose of TPM. Note: p-value calculated employing the two-tailed Wilcoxon rank sum test for equal medians (α = 0.05).
