Background and Aims: Several studies have shown that host genetic factors can be associated with the risk of developing Helicobacter pylori infections. Therefore, we evaluated the most prevalent toll-like receptors (TLRs) polymorphisms in Helicobacter pylori positive subjects and their possible role in susceptibility to Helicobacter pylori infections. Materials and Methods: Using related keywo...

When we are interested in making decisions about best use, comparative therapeutic efficacy, or cost-effectiveness of diabetes technologies such as insulin pump therapy [continuous subcutaneous insulin infusion (CSII)] or continuous glucose monitoring, meta-analysis for the purpose of literature summary is inappropriate and may be misleading. Instead, "decision-making meta-analysis" is more app...
