The data seem to corroborate Dr. Kwasniewski's Optimal Diet, to some extent, in terms of the trend. That is, a higher fat shows a trend towards better health, where as the more protein and more carbs tend towards higher mortalities. At the same time the raw data I have seen so far do not seem to support an idea that plant based very low fat nutrition is healthier!
Dr. Kwasniewski's diet is high in animal fat, low in protein (unlike Atkins) and low in carbohydrates. Similar to Atkins but puts a restriction on protein (1g/kg of ideal body weight, per day) and does not advocate an "induction" stage followed by an increase in carbohydrates.
The following graphs are based on the Raw China Study data , using 1989 part of the study, total M+F, 3-rd "xiang". My original spreadsheet is here in OpenOffice 3.2 Calc format. (Sorry, no Excel, got tired of loosing data). The following graphs represent raw scatter plots for specific disease mortality (all vascular or all cancer) against each of the independent variables, with no data processing of any kind. You be the judge! :)
