you should read this study from Wales, it is another data point which estimates the incidence at 7.8 and prevalence at 75. As far as I understand it, this is very different from Invex's stated numbers, which work on an incidence * 4.3 years to determine prevalence. Whereas, this data from wales would show prevalence = 7.8 * 9.6 years, over double the amount of time with the disease. Could be due to climate or something in Wales, im not sure, but it isn't solely due to obesity
