Changes with aging in gastric biomarkers levels and in biochemical factors associated with Helicobacter pylori infection in asymptomatic Chinese population

Figure 3 Comparison of serum cholesterol levels in various age groups by Helicobacter pylori infection status. In H. pylori-infected subjects, serum levels of TC and LDL were significantly higher in subjects between 55- and 74-years-old compared to those in the 35-44-years-old age group. In non-infected subjects, serum levels of TC and LDL were significantly higher in subjects between 45- and 64-years-old compared to those in the 35-44-years-old age group. The “a” denotes comparison with the 35-44-years-old age group and the “b” denotes comparison with the 45-54-years-old age group, ^aP < 0.05, ^bP < 0.01. H. pylori: Helicobacter pylori; LDL-C: Low-density lipoprotein cholesterol; TC: Total cholesterol.
