Fig. 1 Semilogarithmic plot of the correlation between IgA anti-tTG and EMA scores of 106 patients with biopsy-proven celiac disease consuming a normal diet, 43 celiac patients after a gluten-free diet, and 114 controls. The median (25/75 percentiles) of IgA anti-tTG relative to EMA were as follows: EMA (0), 4 (2/7); EMA (1), 18 (17/23); EMA (2), 105 (43/210); EMA (3), 180 (117/363); EMA (4), 557 (191/762); and EMA (5), 637 (244/1193). r = 0.862; P < 0.0001.

Fig. 2 Semilogarithmic plot of IgA anti-tTG titers of 106 celiac patients on a normal diet (cd), 43 celiac patients after a gluten-free diet (gfd), and of 114 controls (ctr), with the following medians (25/75 percentiles): cd, 199 (118/671); cd/gfd, 18 (5/48); and ctr, 4 (2/7). Differences between groups were significant (P < 0.001).
