title: [Effect of acupuncture therapy on patients with low back pain: a Meta-analysis].
abstract: OBJECTIVE
  To systematically review the clinical efficacy of acupuncture on the patients with low back pain (LBP).
  
  
  METHODS
  Randomized controlled trials (RCTs) about pure acupuncture therapy versus other treatments in treating LBP were electronically searched in PubMed, CBM, EMbase, The Cochrane Library, CNKI, VIP and Wanfang Data from January 2004 to May 2014. The observed index on the results were the changed scores of VAS, ODI, JOA and RMDQ. Two reviewers independently screened the literatures according to the inclusion and exclusion criteria, as well as the extracted data, and assessed the methodological quality. The results of Meta-analysis was conducted by RevMan 5.2 software.
  
  
  RESULTS
  Ten RCTs involved 751 patients were finally included. The results of Meta-analysis indicated that the role of pure acupuncture group in improving the VAS score was better than that of the control group, and the combined effect size was RR = -.32, 95% CI (-1.41, -1.22); Z=27.28, P<0.00001; the role of pure acupuncture group in improving the ODI score was better than that of the control group, and the combined effect size was RR = -5.07, 95% CI (-7.50, -2.65); Z=4.10, P<0.0001; the role of pure acupuncture group on improved JOA score was better than that of the control group and the combined effect size was RR=2.83, 95% CI (2.02, 3.63), Z=6.90, P<0.00001. The role of pure acupuncture group in improving the RMDQ score was better than that of the control group, and the combined effect size was RR = -2.80, 95% CI (-3.49, -2.11), Z=7.95, P<0.00001.
  
  
  CONCLUSIONS
  The result of meta-analysis demonstrates that pure acupuncture may have a favorable effect on self-reported pain and functional limitations in LBP patients.
