Clinical significance of serum thrombospondin-4 for interventional restenosis in diabetes patients complicated by lower extremity arteriosclerosis obliterans

Figure 2 Spearman correlation heatmap of thrombospondin-4 and other clinical parameters in type 2 diabetes mellitus patients with lower extremity arteriosclerosis obliterans. Positive correlations appear in yellow, negative correlations in blue. Color intensity scales with the magnitude of the relationship.
