  1. TB tuberculosis, PTB pulmonary tuberculosis, EPTB extrapulmonary tuberculosis
  2. aregistered in web-based TB information management system
  3. 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)
  4. F stat for model = 9.28; Probability > F = < 0.001
  5. cof 7284, twenty two patient records were excluded because of missing information on dates to calculate delay
  6. ^significant p-value < 0.05
