Randomized Control Trial

 Article 1: Bjornstad, P., Schäfer, M., Truong, U., Cree-Green, M., Pyle, L., Baumgartner, A., … & Nadeau, K. J. (2018). Metformin improves insulin sensitivity and vascular health in youth with type 1 diabetes mellitus: A randomized controlled trial. Circulation138(25), 2895-2907.

  1. The study has clearly stated the goal of the study. The goal of the study was to examine if the use of Metformin in adolescents with type 1 diabetes mellitus (T1DM) improves insulin resistance. The importance of a clear goal is that it informs the readers on the specific aims of the research and prevent the issue of struggling to determine the focus of the study.
