  1. aMean n calculated from full 100,000 simulated population; SD = Standard Deviation.
  2. bMean duration calculated as the mean of all existing transition intervals.
  3. cComparisons of population means between corresponding categories of sparse and dense data are significant at p < 0.0001 in all instances.
  4. dI/O Bed = Getting in or out of bed.
