Table 2.

In both simulation scenarios (I,II): analysed data patterns = A − F, individuals at baseline = 1500, number of simulated data sets = 1000, time between interviews = 24 months, time of follow-up = 12 years. In Scenario I: A₀ = 60, A_b ∼ N(65,2), left truncated at the age of 64 years. In Scenario II: A₀ = 40, A_b ∼ N(74,6.5), left truncated at the age of 64 years.
