Using a cut-off score of 19 for depression on BDI-II, there were no significant associations of BDI scores for any biological marker (morning cortisol: P = .379; resting HR: P = .224; resting systolic BP: P = .424; resting diastolic BP: P = .797; difference [diff] HR: P = .069; diff systolic bp: P = .141; diastolic bp: P = .156; IL-1β: P = .241; and IL-2R: P = .338). The gene discussed is IL2RA; the disease is major depressive disorder.
