Fig. (2) Rates of DD by hs-CRP quartiles. Overall DD and DD2 rates were significantly different among the hs-CRP quartile groups (p=0.03 and p=0.003 respectively). There were significant pair wise differences among the hs-CRP quartile groups 1 and 3 (p=0.008) and groups 2 and 3 (0.001) in the rate of occurrence of any DD.
