Correlation analysis of Se status biomarkers in the mothers and the newborns. Significant positive correlations were observed for all three biomarkers in all possible combinations, both in the full cohort of samples as well as in the groups of mothers (M, left panel) and newborns (N, right panel) separately. The linear positive correlation of (A) Se with SELENOP was most pronounced and stringent, in particular in newborns. (B) Serum Se and GPX3 activity correlated to a similar extent as (C) SELENOP and GPX3 activity. Correlation analyses conducted by Spearman’s R test; linear regression results are indicated as red lines with the 95% confidence intervals as green shadows.
