"Evaluation of Similarity Between Variables by their Native Values and by Proportional Deviations from their Own Exponential Trendlines (pd) -with pd Calculators, Regressions and Visual Analyses - Examples of CHD Subgroups in Different Periods Between 1951-87"

Native' data of Finnish coronary heart disease mortality (CHD) of rural (rur) and urban (urb) subgroups available only by 3-year means, 3ym, from period 1951-87, (for calculation: 1952-88) revealed, that male (M) (M.CHD.rur) in period 1952-77 associated positively with smoking, consumption of alcohol and sugar, but negatively with milk fats), oppositely to (female) F.CHD.rur and F.CHD.urb and mainly oppositely with M.CHD.urb and pig microangiopathy (MAP) (mortality).
