  1. The mean (SD) number of intravitreal aflibercept injections for each subgroup is provided based on those patients receiving intravitreal aflibercept injections in each year. The correlation between letter gain or loss and the number of intravitreal aflibercept is represented by correlation coefficient (r) and associated p-value. The ‘All Patients’ cohort size and mean number of injections administered in year 1 (M12) and year 2 (M24) for each cohort have been included for comparison.
