†”Culture positive” includes all patients with a sputum culture positive for Mycobacterium tuberculosis (MTB). “Not culture positive” includes any patients without a culture positive for MTB, regardless of whether they had a specimen sent for culture or not. “Culture negative” includes only patients with a sputum culture negative for MTB.
‡Compared with culture positive.
