Table 2. Effect of proportion of conventional surgical versus PrePex-based circumcisions on unit cost at the mixed study site.

% conventional surgical circumcisions	% PrePex-based circumcisions	Unit cost
100%	0%	$60*
95%	5%	$60
90%	10%	$60
80%	20%	$61
70%	30%	$61
60%	40%	$62
50%	50%	$62
40%	60%	$62
32%	68%	$63

* This number is different from the unit cost at the routine surgery site because additional equipment and staff were added at the mixed study site, but there was no increase in the number of circumcisions conducted per day.
