Table 4 Estimated risk transition probability with and without intervention and medical utilization.

From: Assessment of possible impact of a health promotion program in Korea from health risk trends in a longitudinally observed cohort

  1. aRisk transition probability was estimated using Markov model order 2, adjusted for age and gender distribution of KNHIC.
  2. bComparing average cost in each T1-T2 risk state pair (e.g. high-medium) to that of the low-low (T1-T2).
  3. cAll probabilities were rounded off at the 3rd decimal place (i.e.0.0014).
