study, non-randomized, also referred to as observational or non-experimental studies, do not use random allocation to assign participants to treatment comparison groups. 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. case-control study cohort study cross-sectional study case report case series randomized study study design.

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.
