In both groups , erythrocyte sedimentation rate and C-reactive protein were elevated ( @ mm/h vs @ mm/h -LSB- P = @ -RSB- and @ vs @ mg/dL -LSB- P = @ -RSB- ) , but only modest correlations were noted between longitudinal and elevated erythrocyte sedimentation rate ( r = @ , P = @ ; confidence interval , @-@ @ ) and C-reactive protein ( r = @ , P = @ ; confidence interval , @-@ @ ) in patients with MR or PE .
