Net benefit for CRP testing by unit cost, test adherence, and cost of AMR. The 3 panels indicate the net-benefit of CRP testing in response to different configurations of the cost of the CRP test, the degree to which health workers adhere with the test results, and the economic cost of AMR per full course of antibiotic averted. The range of colours reflect the net-benefit of the CRP tests, with dark orange areas indicating instances where the use of the test is not cost-beneficial, and dark green areas where the test is most-cost-beneficial. With the exclusion of the costs of AMR ($0), a CRP test would be at best cost-neutral if it was low cost. With the inclusion of the costs of AMR, using either the baseline estimate of $4.1 or a higher estimate of $14, CRP testing would be cost-benficial even if the cost of the test was as high as $3, providing adherence with test results was high
