Notes: LCL = 95% lower confidence limit of corrected Hedge’s g; SD = standard deviation; UCL = 95% upper confidence limit of corrected Hedge’s g.
* p < .05. Effect sizes were calculated using Student’s t test by corrected Hedge’s g (small: from 0 to 0.17, moderate: from 0.18 to 0.43, large: from 0.44 to 0.84).
