First described by Grant and Booth in 2009, a systematised review differs from a systematic review as it does meet the methodological requirements. While some of the elements of a systematic review are included, a systematised review generally only includes one reviewer, may not include extensive searching over multiple databases and may exclude risk of bias assessments.
No methods, standards or guidlelines are available and "typically this type of review is conducted as postgraduate student assignment" (Grant & Booth, 2009).
