In the results section, it is important to include the results of the statistical analysis. Instead of showing the stats, the authors compare % of changes or fold of changes between groups even when the results are not expressed in that way.
I apologize, but I need more information about what you are referring to provide an accurate response. Could you please provide more context or information about the situation you are asking about? Thank you.
Percent of change is common, especially with small samples. There can be inferential statistics, but everything depends on your research question and hypotheses. Generally one does not try to find a test for statistical significance after a study was conducted. Differentiate statistical versus practical significance.
