Methods Decision trees were constructed. The yearly new infection rate in susceptible cohort, using a catalytic model, was estimated. Disability adjusted life year (DALY) was used to assess the effectiveness.

• 方法 建立决策树和乙肝转归树 ,采用催化模型推算不同接种方案下易感人群年新感染率 ,用失能调整生命年 (disability adjustedlifeyear ,DALY)作为衡量效果的指标 ,计算增量成本效果比。
