Fig. 1From: Helicobacter pylori infection: is there circulating vacuolating cytotoxin A or cytotoxin-associated gene A protein?Serum concentration of anti-Helicobacter pylori antibody, vacuolating cytotoxin A, cytotoxin-associated gene A protein and interleukin-12p70. Anti-Helicobacter pylori antibody (a), vacuolating cytotoxin A (VacA) (b), cytotoxin-associated gene A protein (CagA) (c) and interleukin-12p70 (IL-12) (d) were measured using immunoassays. Solid red lines indicate the means, and blue dotted lines indicate upper cutoff values. Statistical analysis by two-tailed unpaired t-test. *p < 0.05Back to article page
