90 CHAPTER 6 SUPPLEMENTAL TABLE 1. Cubic model of the association of collection time with milk cortisol, milk cortisone and the milk cortisone/(cortisol + cortisone) ratio during 24 hours in week 4 postpartum: Study 2 Dependent variable Independent variables ß (95% CI) P -value Cortisol, nmol/L Time 2.62 (1.89 to 3.64) < 0.01 (Time * Time) 0.92 (0.89 to 0.94) < 0.01 (Time * Time * Time) 1.00 (1.00 to 1.00) < 0.01 Cortisone, nmol/L Time 1.65 (1.40 to 1.95) < 0.01 (Time * Time) 0.96 (0.95 to 0.97) < 0.01 (Time * Time * Time) 1.00 (1.00 to 1.00) < 0.01 Ratio Time 0.94 (0.91 to 0.97) < 0.01 (Time * Time) 1.01 (1.00 to 1.01) < 0.01 (Time * Time * Time) 1.00 (1.00 to 1.00) < 0.01 Values are exponentiated betas (95% CI), n = 10 mothers; 92 milk samples. Ratio is calculated as cortisone/(cortisol + cortisone).
