What is the intervention being compared with? (e.g., placebo, standard care, another therapy or no treatment). This section should detail what the intervention of interest is being compared with. The reviewer may wish to examine the comparative effectiveness of two treatments with a specific, head-to-head comparison.  In the example (See Section 3.2.4.3), the reviewers may have specified inspiratory muscle training compared to cardiovascular conditioning. This level of detail is important in determining study selection once searching is complete. Systematic reviews of effectiveness based on the inclusive definition of evidence adopted by the JBI often seek to answer broader questions about multifaceted interventions and comparing the intervention of interest with all existing alternative interventions (comparators).
