WTP thresholds used to assess cost-effectiveness
| Type of threshold | Mumbai | Patna | |
| WHO-CHOICE (based on GNP per capita) | Highly cost-effective | $1500 | $530 |
| Cost-effective | $4500 | $1590 | |
| More stringent WTP* | $290 | $290 | |
The table shows different threshold for cost-effectiveness, used in figures 2 and 3.
*This estimate is drawn from recently published analysis,21 for which only country-level estimates are available. The study used different approaches to propose three different WTP thresholds for India; for simplicity in the present study, we adopt the most stringent of these.
WTP, willingness-to-pay.
