- TB tuberculosis, PTB pulmonary tuberculosis, EPTB extrapulmonary tuberculosis
- aregistered in web-based TB information management system
- blogarithmic transformation of delay variable done as it was not normally distributed, model building was done by stepwise (forward method) method and the final model has been presented; occupation, permanent residence, treatment category and HIV status, though considered, were excluded by the model (likelihood ratio test)
- F stat = 20.8; Probability > F = < 0.001
- cof 7284, twenty two patient records were excluded because of missing information on dates to calculate delay
- ^significant p-value < 0.05
