Figure 2 Comparisons of RRs from 1-h PBT between patients with normal and low serum VB12 levels. Horizontal axis and vertical axis indicate time (min) after 13C-propionate administration. and RR (%dose/h), respectively. VB12 deficiency was defined as serum VB12 level <145 pg/mL. The tinted area around each line indicates standard deviation. There were no significant differences of RRs between the 2 groups. PBT – 13C-propionate breath test; RR – 13C recovery rate; VB12 – vitamin B12.
