Modelling Malaria Mortality in Ghana Using Distributed Lag Nonlinear Frameworks

Francis Ayiah-Mensah, Emmanuel Harris, Mohammed Frempong, Harry Darko Bonsu & Emmanuel Benson · Journal of Advances in Medical and Pharmaceutical Sciences · 2026

Background: Malaria mortality studies in Ghana and sub-Saharan Africa have commonly relied on traditional regression approaches or generalised additive models, which may not fully represent delayed transmission effects, nonlinear exposure-response patterns, or uncertainty in mort...

Open access Research Article 10.9734/jamps/2026/v28i7876

Multi-state and Semi-Markov Modelling of Prostate Cancer Disease Trajectories and Mortality Dynamics

Francis Ayiah-Mensah, Senyefia Bosson-Amedenu, Emmanuel Harris, Mohammed Frempong & Rebecca Nduba. Arhin · International Research Journal of Oncology · 2026

Background: Previous prostate cancer research has often been conducted in clinical or laboratory settings and has relied on traditional survival models that focus on a single disease endpoint. Such approaches do not fully account for intermediate disease states, transition risks,...

A Statistical Framework for Modelling Breast Cancer Disease Pathways with Multistate and Competing Risks Approaches

Francis Ayiah-Mensah, Emmanuel Ayitey, Vivian Nimoh, Mohammed Frempong & Frank Twenefour · Asian Oncology Research Journal · 2026

Background: Breast cancer is one of the leading causes of mortality in women in Ghana; prognostic studies are still dominated by single endpoint Kaplan-Meier and Cox models, which do not consider recurrence, progression, and competing mortality. The study aimed to come up with a...

Modelling Unequal Progress in Reproductive, Maternal, and Newborn Health Coverage, Using Fractional Logit Generalised Estimating Equations (GEE) Analysis

Francis Ayiah-Mensah, Felix Ilesanmi Alao, Senyefia Bosson-Amedenu, Francis Eyiah Bediako & Mohammed Frempong · Asian Journal of Pregnancy and Childbirth · 2026

Background: Universal health is advancing; however, information regarding the distribution of regional expansion in reproductive, maternal, and newborn health services across population groups remains limited. Aims: This study compared the levels of various coverage indicators at...
