STUDY OBJECTIVE To estimate the cost-effectiveness of genotype-guided selection of antiplatelet therapy compared with selecting clopidogrel or prasugrel irrespective of genotype. DESIGN Decision model based on event occurrence in the Trial to Assess Improvement in Therapeutic Outcomes by Optimizing Platelet Inhibition with Prasugrel-Thrombolysis in Myocardial Infarction (TRITON-TIMI) 38. PA...
A recent study reports frequency-dependent survival within highly variable guppy populations. Fitness advantages to rare genotypes may help maintain variation within populations, but the mechanisms underlying these advantages require further study.
Falconer's concept that performance in environment 2 is a different trait from performance in environment 1 allows calculation of expected response in environment 2 if selection is from environment 1. Response to selection in environment 1 and correlated response in environment 2 depend on heritability and phenotypic variance in environment 1, genetic covariance between performance of identical...
The aim of this study was to evaluate the efficiency of yield stability analysis models and to assess genotype × environment interaction effect on grain yield of 20 durum wheat genotypes for identifying high yielding and adapted genotypes by BLU and AMMI models using experimental data of four cropping cycles (2009-2013) in five filed stations in warm rainfed regions of Iran. The results of Like...
The selection efficiency of the most desirable safflower genotypes can be improved by incorporating the graphical methods and statistical analysis. This experiment was carried out to determine grain yield stability of safflower genotypes using the graphical and statistical methods. Twenty safflower genotypes were evaluated in Chachsaran, Choram, Behbehan and Dehdasht using randomized complete b...
GGE (genotype + genotype×environment) biplot is one of the new graphical methods to study genotype×environment interaction in which the effects of genotype and G×E interaction are not separated and selection is based on both of these effects. In the present research, GGE biplot was used to study 14 safflower genotypes over six research stations under water stress and non-stress conditions in sp...
