Figure 1: — Flow diagram, based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline, describing the systematic search for studies of type 2 diabetes and the risk of community-acquired pneumonia (CAP). Note: Some of the studies captured in the literature search evaluated the association between change in glycemic control and risk of pneumonia, in patients with or without diabetes. The estimate derived from these studies did not answer the research question posed in the present study, and thus these studies were not included in the meta-analysis.
