Parallel to this, there are extensions to these guidelines which are little known and used by the personnel involved in research work, they focus on more specific approaches to report different types of studies, among which are: meta-analysis, systematic reviews, clinical trials randomized, diagnostic accuracy studies, observational studies, among others; for this reason, its promotion, knowledge, and use is of vital importance. The objective of this review is to synthesize the main extensions of the guidelines used in medical research; for this purpose, its main characteristics were reviewed, as well as application scenarios according to the level of evidence; Its adequate adherence will allow health personnel involved in research work to increase the transparency and quality of their findings, contemplate potential sources of bias, as well as the development of good practices for the presentation of their results according to the type of study selected.
