Bivariate and multivariable hazard rate ratios for patient characteristics associated with sputum culture conversion among patients with MDR-TB in Georgia, 2009–2011.

Table 2 Abbreviations: IQR-interquartile range; MDR-multidrug-resistant; cHR-crude hazard rate ratio; aHR-adjusted hazard rate ratio; RBG-random blood glucose; AFB-acid fast bacilli; Neg-negative; Dissem-disseminated TB; Bold indicates statistically significant, two sided p-value AAmong patients who converted, median time (days) from MDR TB treatment initiation until first of two consecutive negative sputum cultures ≥30 days apart among patients.BThe adjusted model included all variables with estimates in the aHR column.CAny resistance to a second-line TB drug.DViolated proportional hazards assumptions and not included in adjusted model.EMissing data for this variable was recoded into no/null category.FAll patients were pulmonary, extra-pulmonary includes those with both pulmonary and extra-pulmonary TB.
