highly significantp = 2.8 × 10 −5
A highly significant relationship was observed between the RS and the likelihood of DM whether the RS was treated as a continuous (Wald test; HR = 2.76, Scaled HR; 5.65; p = 2.8 × 10 −5 ), or a binary (log-rank test: HR = 8.25; p = 8.0 × 10 −4 ) variable (Figure 1A ).
