^*(Cases only in NSMD+Matched cases)/(Cases only in NSMD+Cases only in NPR+Matched cases). (Note: In all cases; 104 cases were used as the denominator.)

^†95% CI=Sensitivity±1·96 Var(sensitivity); Var(sensitivity)=(Cases only in NSMD+Matched cases)×(Cases only in NPR+Matched cases)×(Cases only in NSMD)×(Cases only in NPR)/(Matched cases)³.

^‡~100=All, except the single case estimated in the capture–recapture analysis caught by none of the data sources, were captured.
