Table 3.
Sensitivity (percent of patients correctly classified), specificity (percent of normals correctly classified), total (percent correctly classified), likelihood ratios, and post-test probabilities for individual tests, adjusted for age. 95% confidence intervals are in parentheses. Cut-points for normed tests were used as published and described in the Results. Cut-points for FMT were based on ROC analyses as described in the Results.
