Evaluating the NHS Diabetes Prevention Programme

What did the evaluation of the NHS Diabetes Prevention Programme find, and what does that show about this data use?

Read this first: A paper that measures a programme's outcomes is evidence about the programme. It does not show that the data use, or the evaluation, caused those outcomes.

            What remains unknown

            • Whether the evaluation changed the programme: no NHS England decision document citing it has been found or imported.
            • The outcome measured is the programme's effect; recording it as such needs a reviewer to assert a "research evaluated a programme" link from the paper's own methods.
