Table 2 Weighted score assignment

From: Development and validation of a risk score to predict mortality during TB treatment in patients with TB-diabetes comorbidity

Variable β coefficient Adjusted OR (95% CI) P Value Weighted Points
Age ≥ 65 (years) 1.58 4.85 (3.00, 7.85) < 0.001 16
US-born 0.49 1.64 (1.03, 2.62) 0.04 5
Homeless 1.06 2.88 (1.05, 7.88) 0.04 11
IDU 1.98 7.25 (1.64, 31.98) 0.01 20
Chronic kidney failure 1.95 7.00 (3.59, 13.62) < 0.001 20
TB meningitis 1.98 7.25 (1.54, 34.08) 0.01 20
Miliary TB 1.33 3.79 (1.41, 10.21) 0.01 13
Positive AFB smear 0.55 1.74 (1.01, 2.98) 0.04 6
Positive HIV 2.40 11.07 (3.66, 33.46) < 0.001 24
  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
