Those living more than 1.5 kilometers from the center were 3.8 percentage points, or 6 percent, less likely to seek their HIV results than those living within 1.5 kilometers (Table 4, column 5).

The effects of incentives and distance are similar when using a nonlinear model (Table 4, columns 6–10). VCT center attendance varied by HIV status. Overall, HIV-positive individuals were approximately 5.5 percentage points less likely to obtain their results (Table 4, column 1).
