Poisson regressions with general practice random effects. Coefficients are incidence rate ratios.
*P<0.05; **p<0.01; ***p<0.001.
†Coefficients on these variables represent a 1 SD change in the explanatory variables. Column 1 represents the main model as presented in table 2. Columns 2 and 3 represent models including the same indicators of practice clinical quality and accessibility, but alternate indicators for practice resources. Models also include additional practice covariates: practice gender, age, deprivation and ethnicity compositions, practice rurality, type 2 diabetes prevalence, DPP wave, year and wave year interactions; 95% CIs in brackets.
