Model Inputs for One-way Sensitivity Analyses.

aTransition probabilities were derived from Stage I and II colorectal cancer patients (aged 65–69 when diagnosed) who were diagnosed between 1989 to 1993 to give 18–22 years of follow-up data. More details can be found in the File S1.bFor aspirin, the probabilities of fatal and non-fatal adverse events are applied only for the first five years; for capecitabine, probability of 0.0291 for non-fatal adverse events is applied only in the first year. An annual probability of 0 is applied for all other years.cCost of aspirin is applied only in the first five years; cost of capecitabine is applied only in the first year.dThe range for indirect cost is derived by multiplying the lower (−20%) or upper limits (+20%) of the time estimate by the respective applicable lower or upper limits of the median hourly wage.Model Inputs for One-way Sensitivity Analyses.
