Values are shown as n (%) unless otherwise noted. The initial sample included participants with available QIDS-SR scores (N = 3,033). The score cut-off ranges for the QIDS-SR are as follows: Not Depressed: 0–5; Mild Depression: 6–10; Moderate Depression: 11–15; Severe Depression 16–20; Very Severe Depression: 21–27. The suggested level of GlycA is < 399 μmol/L (ie, low risk for cardiovascular disease).
Abbreviations: BMI = body mass index, hs-CRP = high-sensitivity C-reactive protein, QIDS-SR = Quick Inventory of Depressive Symptomatology-Self-Report.
