Comparison of wards covered/not covered by HSfE. The four density plots represent the distribution of the following variables across wards (from left to right): (a) SMR=Inline graphic; (b) Inline graphic, included as a continuous variable (Inline graphic); (c) IMD01, the Carstairs index at 2001; (d) Proportion of non-white individuals. The solid lines are the distributions in the wards with Inline graphic5 individuals sampled by HSfE, while the dashed line the distributions for the wards with Inline graphic5 individuals sampled by HSfE or not covered by HSfE. A similar behavior can be seen for all the variables across wards.
