Cardiology Research and Practice has retracted the article titled “Subclinical Hypothyroidism and Its Association with Increased Cardiovascular Mortality” [1]. The article was previously published as “Hassan, A., Altamirano-Ufion, A., Zulfiqar, B., Boddu, P., Sub-Clinical Hypothyroidism and Its Association with Increased Cardiovascular Mortality: Call for Action. Cardiology Research, North America, 8, May 2017.” The authors appear to have inadvertently mixed up the two journals.
