“low dose” (i.e., <200 mg twice daily) IV thiamine regimens in patients with Wernicke's encephalopathy failed to detect a significant difference in clinical characteristics between the two dosage groups (although an association between higher dose and lower mortality approached but did not reach significance p = 0.061 after controlling for potential confounders) (Nakamura et al., 2018 ).
