non-randomized study GET-IT Glossary.
It is difficult to ensure that treatment comparison groups are sufficiently similar in terms of prognostic variable s in non-randomized studies, particularly prognostic variables that remain undiscovered. There is thus a greater risk of allocation bias in non-randomized studies than there is in randomized studies.

Blinded RCTs are commonly used to test the efficacy of medical interventions and may additionally provide information about adverse effects, such as drug reactions. The terms RCT" and" randomized trial" are sometimes used synonymously, but the latter term omits mention of controls and can therefore describe studies that compare multiple treatment groups with each other in the absence of a control group. 5 Similarly, the initialism is sometimes expanded as" randomized clinical trial" or" randomized comparative trial" leading to ambiguity in the scientific literature. 6 7 Not all randomized clinical trials are randomized controlled trials and some of them could never be, as in cases where controls would be impractical or unethical to institute.

Does the non-randomized controlled study have a place in the systematic review? A pilot study. PubMed NCBI.
A major issue in any systematic review is deciding which trials or studies to include and which to exclude. The Cochrane Collaboration and similar respected organizations have traditionally viewed the randomized trial RCT as the only acceptable evidence on treatment outcome. However, many systematic reviews are indeterminate because they include insufficient RCTs whilst they reject large numbers of non-randomized controlled studies.
