Re: Where's the problem?
The design of appropriate controls will completely depend on what the experiment is. The point is that any systematic errors will be present in both datasets.

If there are 40,000 revenue cameras in the UK each costing £20,000, that’s a total outlay of 800,000,000. Subtract from that the 100,000,000 earned by those cameras and divide that figure by the number of lives saved, gives a value per life of £804,597. NICE by contrast places a figure of somewhere between £20,000 and £30,000 on that same life. Some joined up thinking wouldn’t go amiss…
