title: Chest radiograph in acute respiratory infections in children.
abstract: BACKGROUND
  Chest radiography is widely used in acute lower respiratory infection in children, but the benefits are unknown.
  
  
  OBJECTIVE
  To assess the effects of chest radiography for children with acute lower respiratory infections.
  
  
  METHODS
  We searched the Cochrane Respiratory Infections Group trials register, the Cochrane Controlled Trials Register and MEDLINE up to December 1999. We contacted experts in the fields of acute respiratory infections and paediatric radiology to locate additional studies.
  
  
  METHODS
  Randomised or quasi-randomised trials of chest radiography in acute respiratory infections in children.
  
  
  METHODS
  One reviewer extracted data and assessed trial quality.
  
  
  RESULTS
  We identified only one trial of 522 participants, performed by the reviewers. The participants were ambulatory children aged two months to five years. Forty six percent of both radiography and control participants had recovered by seven days - odds ratio (1.03, 95% confidence interval 0.64 to 1.64). Thirty three percent of radiography participants and 32% of control participants made a subsequent hospital visit within four weeks - odds ratio 1.02 (95% confidence interval 0.71 to 1.48). Three percent of both radiography and control participants were subsequently admitted to hospital within four weeks - odds ratio 1.02 (95% confidence interval 0.40 to 2.60). There were no deaths in either group.
  
  
  CONCLUSIONS
  There is no evidence that chest radiography improves outcome in ambulatory children with acute lower respiratory infection. The findings do not exclude a potential effect of radiography, but the potential benefit needs to be balanced against the hazards and expense of chest radiography. The findings apply to ambulatory children only.
