SNP results from previously published associations of RA susceptibility and the meta-analysis results now GRACE (AutoCure) data has been added.

SNPs allocated to group 1, 2 or 3 based on previously published evidence. The SNPs† in group 2 do not reach genome-wide significance in Stahl et al used in this meta-analysis [6], but have in prior publications [4], [5].αAdditionally, the TAGAP locus has previously been associated with RA at a genome-wide level, however not for the SNP investigated here [19]. Het P = meta-analysis heterogeneity χ2P value, OR = odds ratio calculated using fixed or random* effects meta-analysis.ßPower calculation based on these results assuming 1% disease prevalence in the population.
