Systematic reviews provide a structured summary of the results of trials that have been carried out on any particular subject. If the data from multiple trials are sufficiently homogenous, a meta-analysis can be performed to calculate pooled effect estimates. Traditional meta-analysis involves groups of trials that compare the same two interventions directly (head to head). Lately, however, indirect comparisons and network metaanalyses have become increasingly common. ⋯ Indirect comparisons and network metaanalyses are an important further development of traditional meta-analysis. Clear and detailed documentation is needed so that findings obtained by these new methods can be reliably judged.

Review Meta Analysis
Mind-Body Medicine in the Secondary Prevention of Coronary Heart Disease.
In mind-body medicine (MBM), conventional lifestyle modification measures such as dietary counseling and exercise are supplemented with relaxation techniques and psychological motivational elements. This review studied the effect of MBM on cardiac events and mortality in patients with coronary heart disease (CHD). ⋯ In patients with CHD, MBM programs can lessen the occurrence of cardiac events, reduce atherosclerosis, and lower systolic blood pressure, but they do not reduce mortality. They can be used as a complement to conventional rehabilitation programs.
