The authors' interpretation of the Interval*Group effect in Table 1, with the printed effect size "eta effect value=0.659", which they classify as a "medium rate effect" citing Cohen (1988). Note the printed value would usually be considered large, but the article's own classification is reported here as printed.

"Based on the obtained eta effect value=0.659, the effect that is demonstrated by this eta value is medium rate effect (Cohen, 1988). This explains that the effect of the test/interval interaction with the groups affects the increase in the RCT score at medium level."
