LGALS3 and hydrops fetalis: There is a very strong positive correlation between the assessed variables among the patients in the P+HF+D group, as shown in Figure 5: very strong statistically significant correlations (p < 0.001) were found between GI and PPD (r = 0.9), GI and DPP4 (r = 0.95), GI and Gal3 (r = 0.85), PPD and DPP4 (r = 0.94), PPD and Gal3 (r = 0.86), and DPP4 and Gal3 (r = 0.87).
