Note: Ns for “all comers” at each wave were 1,091 (70 years), 866 (73 years), 697 (76 years), and 550 (79 years). Completers were individuals who remained in the study through Wave 4.
a
Eleven of the completers were absent at Wave 3 (76 years) but returned for Wave 4 (79 years). The corresponding percentages reflect this.
