  1. NBC naïve Bayes classifier, OTM open-source Tariff Method, VA verbal autopsy, MDS Million Death Study
  2. aTraining/testing sample size, with no training required for InterVA-4
  3. bInterVA-4 was evaluated on a testing data set of 50 randomly selected records out of 555 records, in each of the 35 iterations
