Table 4 Coverage estimates and the total number of cases (95% bootstrap-based confidence intervals) for the four pathogens. The presented coverage-estimates are the proportion of reporting laboratories, the catchment population and the area covered by sentinel surveillance (average of the market shares over all NIS5-areas). Participation is set equal to reporting, Belgian laboratory sentinel surveillance

From: Incidence estimation from sentinel surveillance data; a simulation study and application to data from the Belgian laboratory sentinel surveillance
