A The importance of identified fungal proteins in discriminating the BV-positive group from the BV-negative group was determined by an ENSEMBLE bagging decision tree. M5EKD5 (Malassezia sympodialis) was the most important fungal protein distinguishing the BV-positive from the BV-negative group. B An ENSEMBLE bagging decision tree using previously identified important fungal proteins between the BV-positive and the BV-negative state to predict BV status. Candida albicans (A0A1D8PFR4) was selected as the root feature of the decision tree. Each fungal protein on the tree has an iBAQ value unit for cutoff. Each node provides the percentage of the satisfied condition at the node and provides the probability of it not being the BV status of the node
