Fig. 2.

Relationship between mean estimates of the proportion of severe cases treated as in-patients for the two estimation methods. Country specific mean estimates of the prediction biased estimate of severe access to care (${\mathit{\mu }}_{PB}$) is shown on the vertical axis and the mean deaths-adjusted estimate (${\mathit{\mu }}_{DA}$) on the horizontal axis. The concordance correlation co-efficient was estimated as 0.66 with a confidence interval of [0.44–0.8] indicating close agreement between the two estimates. The black line indicates ${\mathit{\mu }}_{PB}$ = ${\mathit{\mu }}_{DA}$ line, and each country is indicated via their country code (Table 2)
