LGALS1 and neoplasm: Analyses of linear correlation between galectins levels and tumor size also found that tumor size was significantly correlated with 90K/Mac-2BP concentrations (r = 0.264, P < 0.001) (Figure 3(a)) and with CEA levels (r = 0.208, P = 0.005) (Figure 3(b)), but no significant correlation was found with galectin-1 or galectin-3 levels (Figures 3(c) and 3(d)).
