title: A Comparison of the Efficacy and Safety of Non-Steroidal Anti-Inflammatory Drugs versus Acetaminophen in Symptom Relief for the Common Cold: A Meta-Analysis of Randomized Controlled Trial Studies.
abstract: BACKGROUND
  Non-steroidal anti-inflammatory drugs (NSAIDs) and acetaminophen are widely used for common cold symptom relief. The objective of this study was to evaluate and compare the efficacy and safety of acetaminophen and NSAIDs in common cold symptom relief using meta-analysis of randomized controlled trial.
  
  
  METHODS
  We searched MEDLINE (PubMed), Cochrane, EMBASE, CINAHL, KMbase, KoreaMed, National Assembly Library, and Riss4u for studies released through June 2012. Two authors independently extracted the data. To assess the risk of bias, the Cochrane Collaborations risk of bias tool was used. The Review Manager ver. 5.1 (RevMan) was used for statistics.
  
  
  RESULTS
  We identified 5 studies. The relative benefit for participants with pain relief was 1.00 (95% confidence interval [CI], 0.96 to 1.05) and I(2) = 0%. The existence of the heterogeneity between studies was not important in this study, thus subgroup analysis was not implemented. The relative benefit for participants with rhinorrhea was 1.02 (95% CI, 0.77 to 1.35) and I(2) = 0%, which also indicates the existence of heterogeneity was not important. The relative risk of adverse events was 1.14 (95% CI, 0.93 to 1.40), I(2) = 0%. There was no apparent asymmetry in the funnel plot.
  
  
  CONCLUSIONS
  There was no difference between NSAIDs and acetaminophen in common cold symptom relief.
