Shа, T., Zhаng, Y., Li, C., Lei, G., Wu, J., Li, X., Yаng, Z., Zeng, C. and Wei, J., 2022. Assоciatiоn оf metformin use with risk of venous thromboembolism in adults with type 2 diabetes: a general-population–based cohort study. American Journal of Epidemiology, 191(5), pp.856-866. Study Abstract (Modified) Metformin is hypothesized to protect against the risk of venous thromboembolism (VTE); however, there is a paucity of data supporting this hypothesis. Among individuals aged 40–90 years with a diagnosis of type 2 diabetes in the Health Improvement Network database (2000–2019), we compared [outcomes of] VTE, pulmonary embolism, and deep vein thrombosis among metformin initiators with those among sulfonylurea initiators. Individuals were followed from their first prescription refill to an incident VTE, drug discontinuation, switching or augmenting, plan disenrollment, or the end of the study, whichever occurred first… Question 1a: What was the purpose of the study conducted by Sha et al?
