Fig. 3. Random-effects univariate meta-regression between treatment failure and esophagitis severity. Each circle represents a study and the size of the circle reflects the influence of that study on the model. The regression prediction is presented by the solid line (1.013 [95% CI, 0.466-1.561], P < 0.001). NERD, non-erosive esophageal reflux disease; ERD, erosive reflux disease.
