How to conduct a systematic review: basic concepts

Gabriela Granja Porto

Considering the lack of financial resources to fund scientific investigations in most Brazilian universities, a viable option found by many investigators is to develop systematic reviews. This type of study consists of a systematized scientific investigation, aiming to perform a critical and thorough literature review. It is located on the top of the levels of evidence pyramid, compared to other types of study (Fig. 1). Reviews with greater visibility are those that respond relevant clinical questions for the professional assisting the population. However, for this to be safe and truthful, they must be organized to avoid biases – both in the selection of studies and extraction and analysis of primary data – that may impair the result.
