Delays of TB patients in three models.

*29 patients of SL and 9 patients of SDC who were never treated in the TB dispensary, so they were excluded from the calculation of treatment delay and total delay. = Mean, M = Median. †Significant difference was found among six sites (Z = 2.659, P = 0.025). SDC was significantly higher than SC (P = 0.040). ‡Significant difference was found among six sites (Z = 3.651, P = 0.005). ZD was significantly higher than SC (P = 0.001) and GN (P = 0.001).
