TABLE 6.

Sensitivity analysis – an independent t test to compare the costs of the two treatment strategies^*

Treatment strategy	Mean cost, $	Mean difference, $	P	95% CI of the difference, $
Sputum strategy (n=19)	2,240±1,620	1,112	0.045	28 to 2,197
Clinical strategy (n=20)	3,352±1,717

^*When the cost of sputum induction was not included in the cost of sputum examination in the SS, the cost of the latter could be $28 up to $2,197 less than the CS
