Comparison of concentrations of cortisol (A) and cortisone (B) and the cortisone-to-(cortisol + cortisone) ratio (C) in paired salivary and milk samples collected during week 4 postpartum. The dashed lines represent the line of equality, and the solid lines the line that best fits the data (Study 2). n = 92 paired samples.
