Fig. 2: Baseline biomarkers of collagen crosslinking (LOXL2), collagen formation (Pro-C3), and collagen degradation (C1M and C6M) in the exploratory cohort.

Tukey boxplots (lines representing 25th, 50th, and 75th percentile with whiskers representing lowest and highest values and *representing outliers defined as 1.5× the 75th or 25th percentile respectively) of LOXL2, C1M, Pro-C3, and C6M levels in those with metastatic (M) and adjuvant (A) disease compared with healthy controls (H). Groups were compared using a Kruskal–Wallis test. Levels of all collagen biomarkers were higher in those with disease, metastatic and adjuvant, as compared with healthy controls. p-Values: * < 0.05, ** < 0.01, *** < 0.001, **** < 0.0001.
