Comment: The quality of evidence is downgraded by study limitations (selective reporting and no blinding, and unclear allocation concealment), by inconsistency (unexplained variability in results).
A Cochrane review [Abstract] 1 included 28 studies with a total of 3 960 subjects. 13 trials reported on acupuncture and 15 trials reported on acupressure. There was no significant difference in pain intensity with acupuncture compared with sham acupuncture (mean difference [MD] -4.42, 95% CI -12.94 to 4.09, 2 trials,n= 325) or standard care (SMD -1.31, 95% CI -2.14 to -0.49, 4 trials, n=495, I² = 93%). It was uncertain if acupressure reduced pain intensity compared with sham control (MD -1.93, 95% CI -3.31 to -0.55, 6 trials, n=472, very low quality) or usual care (SMD -1.07, 95% CI -1.45 to -0.69, 8 trials, n=620, very low quality).
