Table 5 Incremental cost-effectiveness ratios (ICER) of Vitalum groups

From: Cost-effectiveness of tailored print communication, telephone motivational interviewing, and a combination of the two: results of an economic evaluation alongside the Vitalum randomized controlled trial

Outcome Group Costs (euros) Improvement in outcome Difference with next less costly group ICER
     Costs Outcomes  
Difference in total number of guidelines met control 0 0.26 0 0.00  
  TPC 57 0.62 57 0.36 160
  combined 80 0.50 23 -0.12 Dominated by control and TPC
  TMI 107 0.40 27 -0.10 Dominated by control and TPC
Quality-Adjusted Life-Years experienced over 73 weeks control 0 1.07 0 0.00  
  TPC 57 1.09 57 0.02 2,867
  combined 80 1.08 23 -0.01 Dominated by control and TPC
  TMI 107 1.08 27 0.01 Dominated by extended dominance
  1. Note ICER = incremental cost-effectiveness ratio (difference in costs divided by difference in effects of two groups); TPC = tailored print communication; TMI = telephone motivational interviewing; combined = combination of TPC and TMI.
