From: Performance of the Tariff Method: validation of a simple additive algorithm for analysis of verbal autopsies

   Tariff PCVA
   Median 95% UI Median 95% UI
Adult No HCE 34.3 (34.1, 34.5) 29.7 (29.4, 29.8)
  HCE 44.5 (44.2, 44.7) 44.6 (44.3, 44.8)
Child No HCE 28.8 (28.4, 29.2) 36.3 (35.9, 36.6)
  HCE 39.0 (38.4, 39.4) 47.8 (47.1, 48.3)
Neonate No HCE 21.6 (21.2, 22.2) 27.6 (27.2, 28.0)
  HCE 23.9 (23.6, 24.4) 33.3 (32.8, 33.7)
  1. Tariff outperforms or matches the performance of PCVA in the adult module, while PCVA outperforms Tariff in the child module. Results are not comparable for neonates since PCVA can only make cause assignments on six neonate causes, while Tariff makes cause assignments on 11 neonate causes.
