Note. Regression coefficients for linear regression of log-transformed antigen-stimulated IFN-γ production by the QuantiFERON-TB Gold. Wald (t) test statistics are based upon 698 degrees of freedom. P values are not adjusted for multiplicity. Diagnostic plots do not indicate significant departures from normality for the distribution of residuals or nonlinearity in the predictions. The maximum variance inflation factor (<4) is within an acceptable range. CRP: C-reactive protein; AST: aspartate amino transferase; ALT: alanine aminotransferase; SE: standard error; CI: confidence inter.
