In contrast, a systematic review (also a cross sectional study) has been defined as "… a scientific investigation that focuses on a specific question and uses explicit, prespecified scientific methods to identify, select, assess, and summarize the findings of similar but separate studies." (2)

    To minimize mislabeling of systematic reviews, among other purposes, Cochrane Eyes and Vision (CEV) is partnering with individual ophthalmology and optometry journals to appoint a knowledgeable associate editor responsible for editorial functions related to systematic reviews at each journal (http://eyes.cochrane.org/associate-editors-eyes-and-vision-journals).
