From: Estimating correlation between multivariate longitudinal data in the presence of heterogeneity
Estimated unconditional marginal correlation and conditional marginal correlation (given MD at diagnosis > −5 dB and slope of MD > −0.5 dB/year) under 3 simulated scenarios. Scenarios a: different proportions of progressive cases; Scenarios b: different magnitudes of deteriorating rates in progressive cases; Scenarios c: various strength of between-error correlations
