For GWTG-HF, tertiles constituted patients with scores of ≤37 (tertile 1), 38–45 (tertile 2), and ≥46 (tertile 3). For IMRS, 30-day risk categories for females and males were, respectively, low-risk: ≤14 and≤14; moderate risk: 15–19 and 15–18; high risk: ≥20 and≥19; while 1-year risk categories for females and males were, respectively, low risk: ≤8 and ≤10; moderate risk: 9–14 and 11–16; high risk: ≥15 and ≥17.
