Multivariable logistic regression model of predictors of TST positivity in children
Model 1:
aOR (95% CI)
Age 1.22 (1.13 – 1.32), p < 0.001
TB contact score 1.21 (1.09 – 1.34), p < 0.001
Ascaris IgE positive 0.55 (0.28 – 1.07), p = 0.08
Model 2: Interaction between Helminth Positive/Negative and Age
TB contact Score 1.22 (1.10 - 1.34)
Age effect
IgE negative 1.17 (1.08 - 1.27)
IgE positive 1.44 (1.21 - 1.73)
IgE effect
25% age 0.18 (0.05 - 0.67)
50% age 0.30 (0.11 - 0.78)
75% age 0.67 (0.32 - 1.39)

aOR = adjusted Odds ratio, 95% CI = 95 percent confidence interval.
