As presented in Figure 3, the results of the MR analysis were expressed as odds ratios (ORs) of HF per standard deviation (SD) increase in circulating ST2 and galectin-3, indicating that neither genetically predicted ST2 nor galectin-3 were causally associated with the risk of HF (p > 0.05). The gene discussed is LGALS3; the disease is hydrops fetalis.
