When adult/young male, and female deletion-carrying groups were all combined, four medical conditions were significantly more common in AHR than in non-AHR groups: ‘heart valve disease or malformation’ (OR: 10.6 (95% CI: 1.2 to 97.4), p=0.025), ‘anaemia’ (OR: 3.2 (95% CI: 1.1 to 8.7), p=0.027), ‘asthma’ (OR: 2.9 (95% CI: 1.3 to 6.4), p=0.010) and ‘gut problem’ (OR: 4.9 (95% CI: 1.7 to 14.3), p=0.004); of these, only ‘gut problem’ survived Benjamini-Hochberg False Discovery Rate correction (adjusted p=0.1) (online supplemental table 2A, B). Here, AHR is linked to anemia.
