*** $p<0.01$, ** $p<0.05$, * $p<0.1$. The dependent variable in all the models is the change in the quality of the process of stroke care obtained by taking out the within-hospital mean of the variable from the variable. Similarly, the table replaces the composite organisational score with the change in the variable obtained by taking out the within-hospital mean of the variable. Column 3 excludes data relating to London hospitals. Column 4 includes the London dummy, using the full data
