The statistics section includes the description “independent t-tests”. Several such tests have, however, been developed, e.g. Student’s, Satterthwaite’s, Prien’s, etc. Which one was used here?
What does “statistically different” mean?
Univariate – multivariate
The term multivariate is used incorrectly, see e.g. Hidalgo B, Goodman M. Multivariate or multivariable regression? Am J Public Health 2013;103:1-3.
