  1. a Retirement villages and participants deemed ineligible following screening due to inadequate participant numbers with a given village (< 6 individuals). Percentage response rates were calculated as a proportion to the number of expressions of interest received
  2. b Eligibility and ineligibility rates were calculated as a proportion of the response rate
  3. c Randomized rates were calculated as the proportion of the response rate
  4. d Randomized rates calculated as the proportion of the number of expression of interest distributed
