  1. AH, asymptomatic hyperuricemia group; GA, gouty arthritis group; AUC, area under the receiver operating characteristic curve; CI, confidence intervals
  2. Note that the optimal cutoff values of combining D, f (cortex), and R2*(medulla) were not provided due to their dependence on other imaging parameters
