The result of a statistical test is the probability of obtaining a wrong conclusion to the hypothesis by chance. Sometimes it may be difficult to choose the right tools; here I am going to provide some basic guidelines for choosing and understanding statistical tests. I will focus on some ...
AR are metabolised to 3,5-dihydroxybenzoic acid (DHBA) and 3-(3,5-dihydroxyphenyl)-1-propanoic acid (DHPPA), which have longer apparent half-lives and were recently proposed to better reflect long-term whole-grain consumption than the intact AR. The objective of this study was to analyse ...
