Figure 1


Fig. 1 —Scatterplot shows empiric data for erythrocyte sedimentation rate (ESR) for each of 38 patients in our study segregated by whether they had an abscess on MRI. Those 21 patients with abscess are segregated by whether abscess required drainage. Horizontal lines indicate mean ESR values for the 21 patients with abscess and the 17 patients with no abscess (74 and 56 mm/h, respectively). Student's t test indicated that patients with abscess have significantly elevated ESR.
