Health care seeking behavior of TB patients in the three models.

M = Median. †SL was significantly higher than ZD (χ2 = 6.844, P = 0.009), GP (χ2 = 74.037, P<0.001), SDC (χ2 = 11.819, P = 0.001), SC (χ2 = 19.388, P<0.001) and GN (χ2 = 55.892, P<0.001). ZD was significantly higher than GP (χ2 = 49.242, P<0.001) and GN (χ2 = 32.534, P<0.001). SDC was significantly higher than GP (χ2 = 37.521, P<0.001) and GN (χ2 = 22.093, P<0.001). SC was significantly higher than GP (χ2 = 28.015, P<0.001) and GN (χ2 = 14.064, P<0.001). ‡ZD was significantly higher than GP (χ2 = 25.997, P<0.001), SC (χ2 = 24.458, P<0.001) and GN (χ2 = 22.319, P<0.001). SL was significantly higher than GP (χ2 = 42.627, P<0.001), SC (χ2 = 40.911, P<0.001) and GN (χ2 = 38.580, P<0.001). SDC was significantly higher than GP (χ2 = 23.631, P<0.001), SC (χ2 = 22.144, P<0.001) and GN (χ2 = 20.065, P<0.001). §Significant difference was found among six sites (F = 22.386, P<0.001). SL was significantly higher than ZD (p = 0.002) and GP (P<0.001). SDC was significantly higher than ZD (P<0.001) and GP (P<0.001). ZD was significantly higher than SC (P<0.001) and GN (P<0.001).
