Table 2. Summary of the hybrid model simulation results for influenza vaccination strategies.
| Outcome | “Adherence” vs. “Volunteer” [Estimate (95% CI)] |
| Note: The outcome values are for every 1,000 individuals for 5 years.
Abbreviation: CI=confidence interval; CNY=Chinese Yuan; ICER=incremental cost-effectiveness ratio; NMB=net monetary benefit; QALY=quality-adjusted life year; WTP=willingness to pay. | |
