Validating physician-certified verbal autopsy and probabilistic modeling (InterVA) approaches to verbal autopsy interpretation using hospital causes of adult deaths

Table 1 Kappa (κ) statistics for agreement of the three methods among the 145 adult deaths

Methods	κ statistic (total) (N = 145) Kappa (95%CI)	κ statistics (males) (N = 81) Kappa (95%CI)	κ statistics (females) (N = 64) Kappa (95%CI)
InterVA versus HCOD	0.32 (0.30-0.38)	0.27 (0.22-0.30)	0.38 (0.32-0.41)
InterVA versus PCVA	0.42 (0.37-0.48)	0.33 (0.30-0.37)	0.52 (0.47-0.54)
PCVA versus HCOD	0.52 (0.48-0.54)	0.47 (0.44-0.50)	0.57 (0.54-0.60)
InterVA + PCVA+ HCOD	0.41 (0.37-0.48)	0.35 (0.32-0.38)	0.48 (0.44-0.52)

InterVA: probabilistic InterVA model, PCVA: physician-certified verbal autopsy, HCOD: hospital cause of death as the gold standard, CI: confidence interval.
