Whole blood TDP levels were available for 72 of the ALC participants (111.85±32.15 nmol/L, 38 to 199 nmol/L, normal range being 74–222 nmol/L), with 9 ALC participants having whole blood thiamine levels under the clinical cutoff of 74 nmol/L. The total group of ALC did not differ from NC (n=31) on TDP levels t(101)=.64, p=.52). Caine categorized groups differed on TDP levels (F(2,62)=3.29, p=.04), with Caine 2+ having a significantly lower TDP level (100±31 nmol/L, 38 to 148 nmol/L) compared with Caine 0 (126±35 nmol/L, 83 to 199 nmol/L).
