As seen in Figure 3 A,B, there was a highly significant negative correlation (r = −0.304 and r = −0.335) ( p < 0.0001) between the serum VB 12 level and the serum MMA level ( Figure 3 A) or between the serum VB 12 level and the plasma tHCY level ( Figure 3 B) in a given patient, and the serum MMA level directly (r = 0.437) and significantly ( p < 0.0001) correlated with the plasma tHCY level in a given patient ( Figure 3 C). 2.3.
