title: Risk factors for lung infection in stroke patients: a meta-analysis of observational studies.
abstract: BACKGROUND
  The aims of this meta-analysis were to evaluate the risk factors associated with lung infections in stroke patients and to provide evidence for prevention decisions.
  
  
  METHODS
  We searched the Embase, PubMed, EBSCO and Web of Science databases to collect studies from January 2000 to July 2015.
  
  
  RESULTS
  The meta-analysis identified 23 risk factors for lung infections in stroke patients, and the top 5, ranked by order according to odds ratio values (95% confidence interval), were as follows: multiple vertebrobasilar stroke, 22.99 (4.04, 130.83); National Institutes of Health Stroke Scale score >15 points, 14.63 (8.54, 25.08); mechanical ventilation, 10.20 (7.15, 14.57); nasogastric tube use, 9.87 (6.21, 15.70); and dysphagia, 7.50 (2.60, 21.65).
  
  
  CONCLUSIONS
  Preventive measures should be taken against these risk factors to reduce the incidence of lung infection.
