Reasons for “awaiting classification” studies are often inadequate and underreported: a cross-sectional analysis of cochrane reviews

Whenever systematic review authors find a poorly reported study, the decision on whether to include it or not may be inaccurate as enough information does not exist for endorsing its conformity with the eligibility criteria. As the study may contribute to the analysis when the missing information become available, the authors may choose to code it as an “awaiting classification study” (ACS). Therefore, ACS is a study that has been retrieved but cannot be assessed for inclusion until additional information is obtained [1].
