^aTime from 83 HCW participating in at least one LTBI patient encounter along the steps of the cascade
^aCanada is the one high-income country
^bLow-and middle-income countries (LMIC) include: Benin, Ghana, Indonesia, Vietnam
^cSteps 2 & 3 may include HCW time spent on patient education, in addition to placing and reading a TST
