Minor allele is the risk allele, otherwise major allele is associated with risk.

Analysis of time to severe nephropathy (1,361 individuals with 115 events) based on a significance threshold selection criterion of P < 0.01. SNPs with MAF ≤ 5% are excluded. Bias reduction ranges from 43.1% to 80.5%. The final two columns display post hoc power calculations for a similar sample assuming logHRs are set to the value of the naïve or the genome‐wide bias‐reduced estimates.
