Comparison between adequate and deficient plasma vitamin C groups on SUCCAB ratio performance. Participants grouped into adequate (n = 67) and deficient (n = 13) plasma vitamin C groups. Comparison assessed with an ANCOVA analysis, controlling for age on congruent and incongruent Stroop, numbers of medications and years of education on contextual memory and number of medications on delayed recognition memory. Reaction time assessed in seconds. SUCCAB, Swinburne University Computerized Cognitive Assessment Battery; SRT, simple reaction time; CRT, choice reaction time; IREC, immediate recognition memory; Cstrp, congruent Stroop; Istrp, incongruent Stroop; SWM, spatial working memory; CMEM, contextual memory; DREC, delayed recognition memory; significant (p < 0.05).
