Ratio of histidine (His) to urocanic acid (UCA) (median with interquartile range) (a–c) and linear regression between ratio of His to UCA and age of children [(d–f) up to 3 months of age; (g–i) from 3 to 72 months of age] on three body regions. For regression analysis the values were log‐transformed. Age groups: < 48 h (n = 18), 48 h – 4 weeks (n = 18), 1–3 months (n = 21), 4–11 months (n = 20), 12–35 months (n = 25), 36–72 months (n = 30). ***P < 0.001, **P < 0.01 and *P < 0.05 as determined by Kruskal–Wallis test followed by Dunn's multiple comparisons test. b, slope of the regression line; CI, confidence interval.
