Agreement between the four validation methods in determining the causes of children’s deaths
| Methods | AC 1 for all CODs, % (SE) (95% CI) | AC 1 for COD due to SCD, % (SE) (95% CI) |
|---|---|---|
| PCVA coder 1 versus PCVA coder 2 (n = 610) |
54.6 (2.0) (50.7 to 58.5) |
97.4 (0.6) (95.9 to 98.7) |
| InterVA-4 model versus PCVA consensus (n = 610) |
50.6 (5.0) (48.7 to 57.2) |
94.6 (0.9) (95.0 to 99.0) |
| InterVA-4 model versus paediatric ward COD (n = 134) |
42.5 (3.6) (35.4.0 to 49.6) |
96.9 (1.5) (95.0 to 99.0) |
| PCVA consensus versus pediatric ward COD (n = 134) |
50.0 (5.1) (40.0 to 60.0) |
95.5 (1.8) (92.0 to 99.0) |
| PCVA consensus versus laboratory evidence (n = 93) | – | 87.5 (4.4) (78.9 to 96.1.) |
AC1, Agreement coefficient of Gwet; CI, confidence interval; COD, cause of death; SCD, sickle cell disease. SE, Standard error; VA, verbal autopsy.
