Table 3. The most cost-effective strategies (CES) based on different calculation methods.

The cost-effectiveness of 11 strategies were estimated with different methods. Effectiveness was measured with QALY, LYG, and undiscounted QALY.

Calculation methods of cost-effectiveness	First CES	Second CES	Third CES	Sensitive to base case
Base Case	HPV 35–10	Pap smear 35–10	HPV 35–5	-
Life years gained (LYG)	Pap smear 35–10	Pap smear 35–5	Pap smear 30–5	Sensitive
Undiscounted QALY	HPV 35–10	HPV 35–5	Pap-smear 35–10	Sensitive
One-way sensitivity analysis of decreasing sensitivity of HPV DNA	Pap smear 35–10	Pap smear 35–5	Pap-smear 30–5	Sensitive
One-way sensitivity analysis of decreasing sensitivity of Pap smear	HPV 35–10	HPV 35–5	HPV 30–5	Sensitive
One-way sensitivity analysis of decreasing specificity of HPV DNA	Pap smear 35–10	HPV 35–10	Pap 35–5	Sensitive
One-way sensitivity analysis of decreasing specificity of Pap smear	HPV 35–10	Pap smear 35–10	HPV 30–10	Sensitive
One-way sensitivity analysis of increasing sensitivity of HPV DNA	HPV 35–10	HPV 35–5	HPV 30–10	Sensitive
One-way sensitivity analysis of increasing specificity of HPV DNA	HPV 35–10	Pap smear 35–10	HPV 35–5	Not sensitive
One-way sensitivity analysis of increasing specificity of Pap smear	Pap smear 35–10	Pap smear 35–5	Pap smear 30–5	Sensitive
One-way sensitivity analysis based on increasing the cost of HPV DNA	Pap smear 35–10	Pap smear 35–5	Pap smear 30–5	Sensitive
One-way sensitivity analysis based on increasing the cost of Pap smear	HPV 35–10	HPV 35–5	HPV 30–10	Sensitive
