A significant association was detected for HER-2 blockers and HF (p = 0.02), taxanes and SVA (p < 0.0001), immune-checkpoint-inhibitors and pericardial disorders (p = 0.001), epidermal growth factor receptor blockers and/or platins and MI (p = 0.001)—see Table 4 for more details. The gene discussed is EGFR; the disease is hydrops fetalis.
