Data show median and interquartile range [Q1; Q3] in quantitative variables and relative frequency (%) and sample size (n) in qualitative variables. Values without a common letter significantly different, p-Value < 0.05. Quantitative variables were analyzed using the Kruskal-Wallis test, and qualitative variables using the Fisher’s exact test; NPNL = non-pregnant/non-lactating.
