It is important to emphasise that estimates of lifetime risk strongly depend on life expectancy and they cannot be compared across populations unless mortality rates are similar.
Furthermore, variations can be compared across populations, strains or breeds, starting with the variation database and using the "strain polymorphisms" attributes page.
The PGI was the first attempt to develop a tool responsive to individual patients' particular experiences and concerns, and which also converted those highly personal issues to a single Quality of Life (QoL) score that could be compared across populations.
Figure 2 shows how the p-value for each SNP association can be compared across populations (in this case, across race/ethnicities), and triangles indicate direction of the genetic effect (bottom of the triangle is the location of the p-value).
Density is generally a valuable parameter because it can be compared across populations of varying size and geographic scope, and used as an indicator for behavioral ecology and conservation questions relating to, for example, resource density, group structure and dynamics, and hunting pressure [ 31, 48, 49].
Prevalence estimates were age-adjusted by the direct method to the 2000 U.S. population for both NHANES III and NHANES 1999 2000 when seroprevalence was compared across population subgroups.
The mean PCS and MCS at 3 months and 1 year after stroke were compared across populations using ANOVA.
Categorical variables were compared across populations using χ test, and continuous variables were compared using analysis of variance (ANOVA) or Kruskal-Wallis.
Performance and temporal measures could not be compared across sample populations because of the differences in attrition.
