Seth:

Sorry it took so long, but the new graphs are now up.

[...] Whenever back when, I did a post on saturated fat epidemiology from a UK reader, Alex Thorne. He was pretty careful in that — unlike science frauds and grant whores — as an honest guy, he anticipated objections and so constructed and graphed the data in different ways. You can go read that post here. [...]

Alex (& Seth):

Got the graphs and will probably do a new entry, but it may take a couple of days due to being particularly busy on a project (and cooking spaghetti sauce — to go on spaghetti squash, of course).

I’ll drop a not here when it’s up.

I have done this now – thanks for the suggestion – and sent the results to Richard. The trends are still evident – the more saturated fat in the diet the fewer years lost to disease.

Thanks, Richard. Let me repeat that this is really interesting data. Yeah, it’s a perfectly reasonable concern that the small countries are different from the large countries. Changing the data so that you plot “absolute amount of years lost for each country” doesn’t solve the problem, however, because that is a measure where a large country (with, let’s say, 10,000,000 people) will obviously have a larger number than a small country (with say 1,000,000 people). It makes the problem worse, not better.

Here’s a better way to look at these data: make a scatterplot with X = percent saturated fat and Y = disability adjusted lost years per 100,000 population. To see if large and small countries are different, divide the countries into two groups splitting at the median of their population sizes. Then plot large countries with one color of dot (say, red) and the small countries with a different color of dot (say, blue). That will show you if the large and small countries show the same trend. If you want to see even more clearly, fit separate lines to the two sets of points and plot those lines in different colors.

That is a good point. I have spilt the data up – since most of the ‘poorer’ countries are between the far left and just over the midway point on the x-axis and most of the ‘wealthier’ countries are from just over the midway point and on to the far right of the x-axis – and replotted the graphs and the trends for the DALY scores still slope downwards the more saturated fat is consumed for both sub-sets. However, I will concede the degree of the slope is not as steep for the wealthier countries.
