Figure 3 Comparisons of RRs in 1-h PBT between macrocytic and normocytic patients. Horizontal axis and vertical axis indicate time (min) after 13C-propionate administration. and RR (%dose/h), respectively. Macrocytosis is defined as MCV >100 fL. The tinted area around each line indicates standard deviation. RR20 and RR30 were significantly low in VB12 deficiency group compared than in the normal group. MCV – mean corpuscular volume; PBT – 13C-propionate breath test; RR – 13C recovery rate; RR20 – RR at 20 min after administration of 13C-propionate; RR30 – RR at 30 min after administration of 13C-propionate; VB12 – vitamin B12.
