Multiple Logistic Regression Model Predicting Tuberculosis Based on Data Available at Presentation in 207 Adults With HIV and a Positive Symptom Screen

	Adjusted Odds Ratio (95% CI)	Beta Coefficient, Log (Adjusted OR)
ART status
<3 mo	1	0
>3 mo	0.49 (0.24–0.10)	–0.72
No. of symptoms	1.62 (1.09–2.41)	0.48
Duration of symptoms
<14 d	1	0
≥14 d	2.03 (1.10–3.76)	0.71
Temperature, ºC	1.61 (0.97–2.66)	0.48

Number of symptoms and temperature were modeled linearly. Risk score = –19.8 + 0.72 (if ART status >3 months) + (0.48 × No. of symptoms) + 0.71 (if cough >14 days) + (0.48 × temperature).

Abbreviations: ART, antiretroviral therapy; CI, confidence interval; OR, odds ratio.
