Meta-analysis
is a method, using statistical techniques, which combines results from
different clinical studies to obtain a quantitative estimate of the overall
effect of a specific intervention. It is a statistical process for pooling data
from many clinical trials to obtain a clear overview of results. By
statistically combining the results of similar studies, meta-analysis can
improve the precision of the estimates of treatment effect, assess whether
treatment effects are similar in similar situations, and produce a firmer
conclusion than individual clinical studies can provide.
In
the field of evidence-based medicine, the meta-analysis method is at the very top
of the medical-evidence hierarchy, followed by systematic reviews, randomized
clinical trials, clinical trials, pilot studies, cohort studies, case-controls,
case series, case reports, and expert opinions. As clinical trials of
acupuncture as a treatment modality have steadily increased, the number of
meta-analyses concerning acupuncture studies have also reached record highs.
