The Relieving Effects of BrainPower Advanced, a Dietary Supplement, in Older Adults with Subjective Memory Complaints: A Randomized, Double-Blind, Placebo-Controlled Trial
Table 5
(a) Distribution of subjective attention deficit (SAD) symptom severity (using a 5-point questionnaire) in older adults before and after BrainPower Advanced or placebo intervention. (b) Ridit scoring test of the ranked data showed that more people in the BrainPower Advanced group showed reduced SAD (−) and fewer people in the BrainPower Advanced group showed no change or worsened SAD than people in the placebo group after the interventions (). (c) McNemar’s test of the combined data (2 scales) of subjective attention deficit (SAD) shows that BrainPower Advanced intervention, but not placebo intervention, reversed a significantly greater proportion of severe SAD in the older adults. It was noted, however, that BrainPower Advanced group had more severe cases and fewer mild cases of SAD than the placebo group before the intervention.
