  • a Table shows the size of the DES18 and DIS groups for the balanced panel. In total, 7090 practices contributed data for each year of the 10-year study period. Researchers identified different types of participants for the 3-year DES18, distinguishing practices into categories according to the number and order of participation years. For example, a practice that only participated in the first 2 years of DES18 (but not the third year) was categorised as YYN. DIS was only a 6-month scheme. DES18 =Directed Enhanced Service 18. DIS =Dementia Identification Scheme. N =no. Y =yes.
