PRIMEtime CE: a multistate life table model for estimating the cost-effectiveness of interventions affecting diet and physical activity

When I saw Adam Brigg's tweet and thread the figure below stood out.

I have modelled some of the concepts using Hodges' model. I have added some additions, flagging gender* to highlight way this and other factors (often) need to be considered in a multicontextual manner.

There is a lot more of course, including the reference list; for example Squires, et al. which pose some interesting questions.

The first paper is here. It describes the PRIMEtime CE model.

This builds on @Pete_Scarbs and Linda Cobiac's work on the PRIMEtime model (and PRIME before then). My contribution was to add utilities + health & social care costs.https://t.co/B0Fu9uP4ru pic.twitter.com/aGaMcpwIks
