Comparison of the weighted genetic risk score (wGRS) generated using loci associated with the highest risk of rheumatoid arthritis (RA) with the wGRS generated using loci associated with the highest risk of oligoarticular/rheumatoid factor (RF)–negative polyarticular juvenile idiopathic arthritis (JIA) for the purpose of predicting cases of RF‐positive polyarticular JIA (RFposPolys). AUC = area under the curve.
