In order to compare measures of genetic differentiation corrected for differences between populations with different levels of allelic richness and heterozygosity, we calculated standardized FST values with GENODIVE v. 2.0b18 [ 57].
Furthermore, the impact is limited to the urban centre and thus could not affect our conclusions of greater incidence rates compared to the rural centre (or differences between populations with different levels of urbanization in the rural centre).
The present case-control study in Korea found a protective effect of the MTHFR C677T variant genotype for gastric and colorectal cancer and suggested that the effects of the MTHFR C677T genotype may differ in populations with different levels of folate intake.
Furthermore, when combining data from different experiments and populations with different levels of performance, the mixed model will automatically adjust for differences in the mean of these populations and/or experiments.
The magnitude of benefit of H pylori eradication in populations with different levels of gastric cancer risk and in different clinical scenarios is unclear.
The study area is characterized by rural populations with different levels of urbanization: higher urban vs. rural population densities (Bohicon district); higher rural vs. urban population densities (Allada district); and only rural population (Toffo district).
Studying other populations with different levels of pulmonary inflammation would also give useful information and hence help us to understand whether 18F-FDG has more general utility for imaging lung inflammation.
In a phase III trial, a dengue vaccine has been shown to be effective against clinical dengue and has proven twice as effective in individuals with preexposure to natural dengue (8), providing an important input for modeling vaccination in populations with different levels of dengue exposure.
