Box-and-whisker plots of SMAP assessed by AUC in diabetic patients with normoalbuminuria and albuminuria, treated with or without aspirin. Box-and-whisker plots of SMAP assessed by AUC in diabetic patients with normoalbuminuria and albuminuria, treated with or without aspirin. In these plots, lines within the boxes represent median values; the upper and lower lines of the boxes represent the 25th and 75th percentiles, respectively; and the upper and lower bars outside the boxes represent the 90th and 10th percentiles, respectively. Kruskal-Wallis test: P < 0.001, *P < 0.001 vs. normoalbuminuric patients treated with and without aspirin, †P = 0.01 vs. albuminuric patients without aspirin (Mann-Whitney U test).
