In line with expectations of the sustainable development goals [SDG 10; United Nations, 2015 (Goal 10)], aimed at bridging inequities across all aspects of society [9,10], including inequities in health and healthcare, we set out to derive metastasis-predicting models for the Ghanaian context and compared the performance of the novel multiparametric model to that of a PSA-alone model in predicting metastasis in prostate cancer patients in Ghana. The gene discussed is KLK3; the disease is prostate cancer.
