¹Pain measure transformed using Log10

²CESD transformed using square root.

³Variance components for rate of change were not estimated when the model did not include the random effect

⁴Covariance between initial status and rate of change were not calculated because the random effect for rate of change was excluded.

⁵Due to rounding, values look like 0.
