Fig. 3From: The effect of sampling health facilities on estimates of effective coverage: a simulation studyEstimates of input- and quality-adjusted coverage of labor and delivery care using original quality scores, by ecological linking method and facility sample size. The red line indicates the input- or quality-adjusted coverage based on exact-match linking. Light red lines indicate the 95% CI around the exact-match coverage estimate. Green (input-adjusted) and blue (quality-adjusted) dots indicate the coverage estimate derived from the ecological linking method applied to the census of providers. Light green (input-adjusted) and light blue (quality-adjusted) bars indicate the 95% CI around the census-derived ecologically linked effective coverage estimates. Gray dots indicate the effective coverage estimates produced using each of the 20 samples by sample size and ecological linking methodBack to article page
