Dr. Carel le Roux and other researchers from Imperial College London conducted the research on this topic. The sponsor was undisclosed. Finding some sort of cure or remedy for diabetes, or perhaps any other health benefits from getting weight loss surgery was most likely the main focus of the sponsor. Some methodologies for this study were given, such as the size of the study group, which was 209 people who chose to undergo weight loss surgery (gastric bypass, sleeve gastrectomy, and gastic banding). The results of the assessment were given in percentages of the people who chose to undergo specific surgeries and are clearly stated in the article. No graphs were used in this article.
