Indicators included in the InterVA model but missing from WHO verbal autopsy adult tool. The majority of missing indicators are disease conditions in adults and variables from the treatment section of the WHO adult questionnaire. Conversely, indicators in the model are not accounted for in the WHO data collection tool.

Spreadsheet showing cause of death categories assigned by the HCOD, PCVA, and InterVA model. The spreadsheet shows varying causes of death for each method. These were further categorized into broader cause groups referred to as the "condensed common list" to match each other, especially for causes without direct correlates. Diseases with fewer frequencies were also regrouped; mapping was then done and a common list was generated (collapsed COD list) for easy comparison.

Pattern of misclassification error: comparison of InterVA model causes of death versus the hospital cause of death. The table shows patterns of misclassification of cause of death (COD) between InterVA model versus hospital cause of death (HCOD). Misclassification was observed among all COD.
