In contrast to the study-reported results, HomVEE calculations showed this difference to be statistically significant (p ≤ 0.05). The HomVEE tests of statistical significance are based on the HomVEE calculated effect sizes, whereas authors may have used other techniques to determine statistical significance, such as regression models or analyses of variance (ANOVA).
