Definition of abbreviation: Q = quartile.
Values are means (SD) unless otherwise noted. Sex-specific quartile ranges for galectin-3 concentrations are as follows: for men, Q1 = 3.9–11.1 ng/ml, Q2 = 11.2–13.1 ng/ml, Q3 = 13.2–15.4 ng/ml, Q4 = 15.5–54.4 ng/ml; for women, Q1 = 5.0–12.0 ng/ml, Q2 = 12.1–14.3 ng/ml, Q3 = 14.4–16.8 ng/ml, Q4 = 16.9–52.1 ng/ml.
