  • 1-150 Patients were treated with vitamin B12 before measurement.

  • Laboratory findings: RBC=erythrocyte counts (normal 4–5.3 million/ul); MCV=mean cell volume (normal 80–100); Vit B12=serum vitamin B12 concentrations (pg/ml; normal >160 pg/ml); Schilling test (normal extraction >9%). Clinical findings: disability: no=0; mild=1; moderate=2; severe=3 (only gait: bed/wheelchair bound=4); Lt=light touch; pp=pin prick; Vib=vibration sense; Pos=position sense; Pyr tr=pyramidal tract damage; Mental = mental impairment.
