Probability decay function for the MIS survey showing probability of attendance ( y -axis) for treatment seeking group against increasing travel times ( x -axis); Y = C/(1 + e(A-x)/B) where C (0.766) is the limiting function on the y -axis; A (3.736) is the asymptote factor at the inflection point of the model; B (-0.609) is the decay parameter. The model was run using log transformed travel time ( x -axis) and later back transformed for presentation purposes. The attendance pattern (1 = attendance and 0 = non-attendance) is also superimposed on the decay curve. The coefficient of all parameters were significant at p < 0.001.
