Fig. 1From: GDF-15 plasma levels in chronic obstructive pulmonary disease are associated with subclinical coronary artery diseaseCAC scores & GDF-15 plasma levels by sex. CAC scores were determined by analysis of non-EKG-gated HRCT and GDF-15 plasma levels were measured by ELISA. a, CAC scores, as Agatston Units; b, GDF-15 concentrations, as pg/mL. Data are median (bar), 25th & 75th percentiles (box), 5th & 95th percentiles (whiskers) with outliers shown as individual points. p-values by Mann-Whitney testBack to article page
