GENERAL ARTICLES A narrative on the fabrication of results in science João Freitas*, Dulce Esteves and Henrique Neiva Data fabrication is an act of scientific misconduct that affects its transparency and veracity. In this study we identify the main data fabrication problems in scientific research and suggest prevention methodologies. This article is a narrative review of the major articles in fabrication of results in science. The results of this review provide the knowledge that fabrication cases come from most diverse scientific fields. Currently, there is more pressure on scientists to publish. As a result, several studies now report on data fabrication in research. State laws and research ethics committees strengthen relationships to criminalize this type of misconduct that usurps state funds. This study dis- cusses the controversies and complexities of data fabrication in scientific research. Ethics commit- tees must continue their efforts to prevent data fabrication, thus contributing to scientific transparency.

Thus, the present study reviews the results of data fabrication in science. João Freitas is in the Sport Science School of Rio Maior, Polytechnic Institute of Santarém, Portugal; Dulce Esteves and Henrique Neiva are in the University of Beira Interior: Department of Sports Sciences, Methodology UBI, Covilhã, Portugal and Research Centre in Sport Sciences, Health Sciences and Human Development, Portugal.

There is a notion that fabricated results tend to be uncov- ered due to the self-regulatory mechanism of research regulation25.
