Receiver operating characteristic (ROC) curves for block 1–4 predicting contraceptive use, Uganda 2010. Block 1 (enabling factors): area under curve = 0.58. 95 % CI (0.50–0.66), p = 0.06. Block 2 (predisposing factors): area under curve = 0.66, 95 % CI (0.59–0.73), p < 0.001. Block 3 (relationship factors): area under curve = 0.74, 95 % CI (0.68–0.81), p < 0.001. Block 4 (need): area under curve = 0.76, 95 % CI (0.70–0.82), p < 0.001. The dotted lines are the ROC curve for each block. The solid diagonal line is the line of no discrimination
