Bookshelf To avoid this, we included the sex of patients as a variable of adjustment in the survival model and, finally, sex did not significantly influence the occurrence of cancer at 60months. The proportional hazard assumption was checked with 2 different methods: graphically by plotting the log(minuslog) curves and by studying the interaction with time. Compared to the NN group, a persistent elevated plasma B121000ng/mL was strongly associated with the occurrence of solid cancer (HR 5.90 [95% CI 2.7912.45], p<0.001), contrary to non-persistent plasma B12 elevation (p=0.29). So keep reading we are going to get into the details. In some people, high levels of B12 may cause gastrointestinal problems such as bloating and diarrhea. As the cell membranes are damaged there are a cascade of inflammatory molecules produced. & Nexo, E. Unexpected high plasma cobalamin/Proposal for a diagnostic strategy.
