Table 3. Average BE thickness measured by OCT before RFA predicts the presence or absence of residual glands measured by OCT immediately after RFA.

Absence of Residual Glands Immediately after RFA Presence of Residual Glands Immediately after RFA Total
Average BE Thickness < 333 μm 11 3 14 PPV = 78.6%
Average BE Thickness ≥ 333 μm 1 17 18 NPV = 94.4%
Total 12 20 32
Sensitivity = 91.7% Specificity = 85% Accuracy = 87.5%
