  1. Numbers of events do not add up, because only the first event in each category was analysed. Letters coding the haplotypes refer to the rs2768762, rs2644620, rs12566888, rs2768744, rs6671392, rs822441, rs11264581, and rs12137505 alleles, respectively (see Additional file 1: Tables S1 and S2). Haplotypes were reconstructed using the expectation-maximisation algorithm as implemented in the PROC HAPLOTYPE procedure of the SAS software version 9.4. Haplotypes with a frequency of ≥10% were carried forward in the analysis. Hazard ratios (95% confidence interval) express the risk of haplotype carriers vs. non carriers. Hazard ratios account for family clusters, and were adjusted for baseline characteristics including sex, age, body mass index, mean arterial pressure, total-to-HDL cholesterol ratio, smoking and drinking, antihypertensive drug treatment, and history of cardiovascular disease and diabetes mellitus
