Figure 3From: Impact and cost-effectiveness of chlamydia testing in Scotland: a mathematical modelling studyIncremental cost per QALY gained if partner notification efficacy is changed from baseline (0.4). Overall testing coverage is 16.8%. Note that there is no valid cost per QALY gained for the baseline strategy (0.4 partners notified and tested/treated per treated positive index; indicated by the vertical line on the figure). Calculations are for equilibrium state. For table accompanying this Figure see Additional file 1: Table S3.Back to article page
