The dependent variable was total platelets count. The independent variables were age, sex, BMI, serum cortisol following 1 mg-DST, smoking habits (current, former, and no smokers). Significant P-values are highlighted in bold (r2 = 0.169, P = .009).

Abbreviations: 1 mg-DST, serum cortisol following 1 mg dexamethasone suppression test; BMI, body mass index; CI, confidence interval.
