| King-Lu (KL) does not estimate individual causes so chance-corrected concordance and Cohen's kappa cannot be calculated. | |||||||||
Table 1 shows chance-corrected concordance (CCC), and cause-specific mortality fraction (CSMF) accuracy for all methods across 500 splits by age and health care experience for adults, children, and neonates. CI, confidence interval; KL, King-Lu; PCVA, physician-certified VA; RF, Random Forest; SSP, Simplified Symptom Pattern; VA, verbal autopsy.
