Spearman’s rank correlation coefficient and correlation significance of the proteins. Protein expression score was used to calculate Spearman’s rank correlation coefficient and significance; correlation coefficient, Spearman rank correlation coefficient; P value, Spearman correlation; , P < 0.05 (significant correlation); , P < 0.01 (highly significant correlation). Spearman’s rank correlation test.
