In both groups , erythrocyte sedimentation rate and C-reactive protein were elevated ( 85.336.2 mm/h vs 75.133.1 mm/h [ P = .34 ] and 12.36.7 vs 11.78.2 mg/dL [ P = .83 ] ) , but only modest correlations were noted between longitudinal and elevated erythrocyte sedimentation rate ( r = 0.52 , P = .01 ; confidence interval , 0.10-0 .80 ) and C-reactive protein ( r = 0.50 , P = .02 ; confidence interval , 0.10-0 .80 ) in patients with MR or PE .
