Fig. 1 The percentages of 80 individuals in the first study who had either low (below the lower limit of reference range, n = 39) whole-blood thiamine diphosphate levels or normal (n = 41) whole-blood thiamine diphosphate levels are shown. The patients are grouped by the finding of high (above the upper limit of reference range, n = 42) serum folate or normal (n = 38) serum folate levels (χ2 statistic, P < .01).

Fig. 2 The RYGBS is depicted in this adapted diagram. The orientation of the gastrojejunal anastomosis may be different, depending upon whether an open or laparoscopic technique is used during the surgery. The location of the jejunojejunal anastomosis may vary depending upon whether a long or shorter common small intestinal channel is formed at surgery.
