  1. NBC naïve Bayes classifier, VA verbal autopsy, OTM open-source Tariff Method
  2. aOur earlier publication demonstrates that the performance of our OTM to the original Tariff method is comparable [8]; the OTM performed almost exactly as the original Tariff method on the hospital-based dataset without the health care experience (HCE) variables (for the top cause), but less well than the same analysis with HCE variables. Note that results in the original Tariff publication without HCE were only available for the top assigned cause [7]. HCE variables are those that capture any information that the respondent may know about the decedent’s experiences with health care
