found that a marginally significant decrease in SBP ( p = 0.05) associated with oral thiamine for 3 months was only observed in subjects (> or = 65 y) with persistently low erythrocyte thiamine pyrophosphate concentrations ( n = 35), and no obvious effect was found in subjects without persistently low RBC thiamine concentrations ( n = 41) [ 20 ].
