The frequency of myeloid blood malignancy did not differ between the EN and NN groups, and chronic liver disease was more common in the EN group than in the NN group. The site is secure. In this study, we limited the analyses to cancers occurring within 60months following B12 measurement, because it appeared to be difficult to establish the causal link between a subclinical solid cancer and an elevated plasma B12 beyond a period of 5years32,33,34,35.
