Figure 2 The effect of EoE prevalence on the PPV and NPV of esophageal rings for diagnosing EoE. The sensitivity and specificity of esophageal rings are held constant at 48% and 91%, respectively (these are the values calculated with a random-effects meta-analysis in this study). The prevalence of EoE is varied on the x-axis, and the resulting PPVs or NPVs are noted on the y-axis.
