The Grading of Recommendation, Assessment, Development, and Evaluation (GRADE) tool was used to assess the certainty of the evidence for the two primary biochemical outcomesserum vitamin B12 concentration increase and homocysteine reductionacross all included studies, and separately for randomised controlled trials (RCTs) and observational studies
Gastric banding carries a lower B12 deficiency risk than malabsorptive procedures, as the absorptive anatomy remains largely intact after LAGB
Supporting cancer therapy Studies show that NNMT can affect cancer development and growth
