^a All probabilities are derived from the LHSC data set except the probability of having voice issue right after the initial MT
^b Only non-zero probabilities are listed. All probabilities for the remaining branches in the model are zero
^c PSA: probabilistic sensitivity analysis
^d The parameter α for beta distribution equals the number of occurrence
^e The parameter β for beta distribution equals the difference of sample size and number of occurrence
