Table 1 Vitamin B 12 , folate and homocysteine levels in H. pylori -positive and negative patients with functional dyspepsia

From: Relationship between vitamin B12, folate and homocysteine levels and H. Pylori infection in patients with functional dyspepsia: A cross-section study

Variable Concentration P value*
  H. pylori positive H. pylori negative  
  (n = 80) (n = 50)  
  Mean ± SD/median (IQR) Mean ± SD/median (IQR)  
Vitamin B12 (pg/mL) 357 ± 170/350 (240) 313 ± 136/290 (170) 0.13
Folate (ng/mL) 4.35 ± 1.89/4.6 (2.85) 4.42 ± 1.93/4.5 (3.32) 0.84
Homocysteine (μmol/L) 15.88 ± 8.97/13.84 (8.97) 16.62 ± 7.82/14.5 (7.62) 0.24
  1. *The Mann–Whitney test was used to compare mean homocysteine levels in H. pylori positive vs. H. pylori negative groups, while an independent sample t test was used for comparison of mean concentrations of vitamin B12 and folate between H. pylori positive and H. pylori negative groups.
