Demonstration of the possible clinical influence of the clinical decision-making tool derived from the random forest model. The probability of achieving treatment success following MOWHTO is 98.0% (left) and 42.0% (right). Factors marked in blue positively affected this patient’s ability to achieve treatment success. Factors marked in red had a negative impact.
