Costs are in CNY¥ except those in parentheses, which are the equivalent costs in USD$. The costs in US dollars were converted based on purchasing power parity according to the International Monetary Fund. (1.00 USD as 3.92 CNY) [22]
The γ-distribution was used for costs, of which the standard deviation was set the same as the mean value
^aThe range of fluoride varnish treatment cost in one-way sensitivity analysis was set as ± 20% of the base case value
^bItems selected to be involved in certain cases are marked by a dot. If an item was charged multiple times in the treatment, it was marked by the number instead
