Preliminary Study to Evaluate Three Different Treatments on Stable Chronic Obstructive Pulmonary Disease Patients Based on Markov Model

Figure 5

Univariate sensitivity analysis between combined group and TCM group. The results show that parameters vary independently within the range of sensitivity analysis except p_t12, p_t1234, p_ae_c34z, p_ae_t34z, u_s_t34, u_s_c34, u_s_c12, u_s_t12, p_c12, and c_s_c34, and the ICUR is always less than the social willingness-to-pay. With parameter p_t12 fluctuating in its sensitivity analysis range, ICUR is less than two times of social willingness-to-pay all the time. With u_s_t12, p_c12, p_t1234, and c_s_c34 fluctuating in the range of sensitivity analysis, the ICUR may exceed three times of social willingness-to-pay. With p_ae_c34z, p_ae_t34z, u_s_t34, and u_s_c34 fluctuating in the range of sensitivity analysis, ICUR will be less than zero if the utilities of combined group were lower than the TCM group.
