  1. Weighted points of a risk factor were calculated using a linear transformation of the corresponding β coefficient [divided by the smallest β coefficient (0.49, US-born), multiplied by a constant (5), and rounded to the nearest integer] [21]
  2. Risk score = 16*[Age ≥ 65] + 5*[US-born] + 11*[Homeless] + 20*[IDU] + 20*[Chronic kidney failure] + 20*[TB meningitis] + 13*[Miliary TB] + 6*[AFB-positive smear] + 24*[Positive HIV]
  3. IDU injecting-drug user, AFB acid-fast bacilli
