“Selection of statistical tests influences the interpretation of a study outcome” a comment on “Giriraja KV, Bhatnagar SK, Tomlinson L, Sancilio F. An open-label, multicenter, phase 2 study of a food enriched with docosahexaenoic acid in adults with sickle cell disease. Prostaglandins Leukot Essent Fatty Acids. 2023 Jun; 193:102574.

Parametric tests such as t-tests require a normal distribution of data. However, the determination of normal distribution may not be conclusive while dealing with a small sample size. Non-parametric tests such as Wilcoxon tests may be used in this situation, as these tests do not require normal distribution.
