^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; age group, gender, occupation, permanent residence, treatment category and registration at referral hospital, though considered, were excluded by the model (likelihood ratio test)
F stat for model = 43.6; Probability > F = < 0.001
^cof 7284, twenty two patient records were excluded because of missing information on dates to calculate delay
