Binomial Logistic Regression. B, regression coefficient; OR, Odds Ratio; CI, Confidence Interval. QFT-GIT, QuantiFERON-TB Gold In-Tube; TB, tuberculosis; LTBI, latent tuberculosis infection; 25(OH)D, 25-hydroxyvitamin D; Ag-TB, antigen-dependent response; PHA, mitogen-induced response. ^*In this table, children with Mediastinal TB were not included in the active TB cases.^†Cytokine levels were multiplied x10. Bold values, statistical significative values with a p-value under 0.05.
