After full adjustment, compared with individuals in Q1, AIP was still inversely associated with HF in Q2 (OR = 0.44, 95% CI = 0.24–0.82, p = 0.0099), Q3 (OR = 0.27, 95% CI = 0.13–0.54, p < 0.001), and Q4 (OR = 0.44, 95% CI = 0.19–0.99, p = 0.032). This evidence concerns the gene AIP and hydrops fetalis.
