Similarly, the Pearson correlation coefficient (r) correlating vitamin B12 with anti-Tg antibody levels was -0.253, showing a negative correlation between vitamin B12 and anti-Tg antibody levels (r (98) = 0.253, p = 0.011), implying once again, increasing prevalence of vitamin B12 deficiency in patients having raised levels of anti-Tg antibodies. Here, TG is linked to vitamin B12 deficiency.
