Table 3 Adjusted incremental costs, effectiveness, and cost-effectiveness ratios

From: Cost-effectiveness of chronic fatigue self-management versus usual care: a pilot randomized controlled trial

Intervention Incremental cost (95% CI) Incremental effectiveness (95% CI) ICER
Imputed effectiveness data, 12 mo    
UC Reference Reference Reference
FSM -$1729 (−5125,1095) 0.73 (0.15, 1.42) FSM dominant
Complete cases, 12 mo    
UC Reference Reference Reference
FSM -$1464 (−6670,3350) 1.22 (0.16,2.55) FSM dominant
  1. UC = Usual Care; FSM = Fatigue Self-Management; CI = Confidence Interval.
  2. ICER = Incremental Cost-Effectiveness Ratio, in 2010 US dollars; ICER = −2358 for imputed data, and −1199 for complete cases. Because the magnitude of negative ICER do not convey the same information as positive ICER do, "FSM dominant' is reported to indicate that FSM is more effective at lower costs as compared to UC.
  3. Effectiveness and costs were obtained from multivariate regression models adjusting for the following baseline characteristics: age gender, education, marital status, employment status, number of chronic conditions, and number of symptoms.
