Factors significantly up-regulated in malignant vs. benign seroma profiles. a Relative expression of cytokines up-regulated in malignant post-operative seroma fluid compared to benign seroma. b Leptin expression in benign and malignant seroma fluid presented collectively and as BMI-matched groups. c Distribution of BMI among patients in benign and malignant groups. d Pearson correlation analysis showing a significant positive correlation of leptin expression with BMI [Pearson r = 0.6422; p < 0.0001, n = 48 (all benign and malignant seroma samples where data is available)]
