RARRES2 and hydrops fetalis: After exclusion of cases that occurred during the first 2 years of follow-up (n = 2335) from the analysis the associations between chemerin (HR per doubling chemerin: 4.89; 95%-CI: 2.49–9.61; p < 0.0001) and omentin-1 (HR per doubling omentin-1: 1.39; 95%-CI: 0.90–2.13; p = 0.14) concentrations and the risk of HF in the overall population remained unaltered.
