Table 3: Effects of polyphenolic compounds from pine bark extract on CPT-III in attention-deficit hyperactive disorder participants.
Values are expressed as the mean ± SD. B: baseline, before supplementation; P: placebo, 4-week supplementation with maltodextrin and magnesium stearate; PE: 4-week supplementation with polyphenolic compounds from pine bark extract; CPT-III: continuous performance test III; HRT: hit reaction time; HRT-SD: hit reaction time-standard deviation; HRT-BC: hit reaction time-block change; HRT-ISI-C: hit reaction time-inter-stimulus interval-change.
