FIGURE 2.

Mortality rate means, differences, and effect sizes in low versus high elevation jurisdictions. Statistically significant differences, along with very large effect sizes were found between low and high elevation jurisdictions for all-causes mortality rates (p < 0.0001, effect size = 1.3), heart disease (p < 0.0001, effect size = 2.5), cancer (p < 0.0001, effect size = 2.1). Diabetes mortality was lower in higher elevation jurisdictions but this difference was not statistically significant (p = 0.1) with a small-medium effect size (0.4).
