Partial η2 was used to measure the effect size as either small (0.01 ≤η2 <0.06), medium (0.06 ≤η2 <0.14) or large (η2 ≥0.14).22
Cognitive impairment was assessed using the Mini-Mental State Examination with scores of 21–28 and 10–20 out of 30 indicating mild and moderate cognitive impairment, respectively.14
