However, with UFF + UFE as the outcome, total [R.sup.2] in women increased to 0.72 and--in addition to urinary nitrogen--plasma leptin also explained a significant portion of variation of potential fGcA after adjustment for glucocorticoid secretion (GC3; Table 1).
With both UFF + UFE and UFF (the conventional measure for fGcA), increases in the protein intake-related postmeal plasma cortisol, as reported in the literature, are mirrored by the significant positive [beta] values for 24-h nitrogen excretion rates.
