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

Figure 4

Univariate sensitivity analysis between combined group and Western medicine group. The results show that parameters vary independently within the range of sensitivity analysis except c_s_c34, p_ae_c34z, u_s_c34, p_ae_w34z, and u_s_w34, and the ICUR is less than the social willingness-to-pay all the time (1 time per capita GDP = 78 951.15 Yuan). With c_s_c34 fluctuating in its sensitivity analysis range, ICUR is less than two times of social willingness-to-pay all the time. With p_ae_c34z, u_s_c34, p_ae_w34z, and u_s_w34 fluctuating in the range of sensitivity analysis, ICUR will be less than zero if the utilities of combined group were lower than the Western medicine group.
