Conditional information

In the underlying study performed by Traister et al. (2015) in 148 patients, a cutoff score of 4 gave a sensitivity of 83%, a specificity of 95%, a positive predictive value of 96%, and a negative predictive value of 77% and, given the balance of sensitivity and specificity, was determined to be the best cutoff for distinguishing VCD from asthma. By using prediction profiling, a cutoff score of 4 would give a 77% probability of having VCD.
