Thanks Slim, I am aware of the big studies.
What I need to know, is if it's worth dropping something, (take your choice: smoking cessation, hip relplacements, air ambulances), to spend extra time measuring hips, for a net health gain?
(If "Clinical Judgement" and BMI is the initial pointer, then we'll have to measure a lot of hips)
Sorry, haven't got the answer, and I'm not sure that the big studies do either
Which is why, perhaps, I'm (over)relying on N.I.C.E.
