  1. Data are mean number per patient (standard deviation) and difference (standard error). P-value is from the linear mixed model. CI confidence interval
  2. Note: The ‘one year before diagnosis’ field includes the index admission which accounts for the mean number of emergency admissions being above one in this time period
