Correction: The effects of melatonin supplementation on blood pressure in patients with metabolic disorders: a systematic review and meta-analysis of randomized controlled trials (Journal of Human Hypertension, (2019), 33, 3, (202-209), 10.1038/s41371-019-0166-2)

In the original Review Article, it was discovered that there were methodological issues that invalidated the reported results of the meta-analyses performed in the study, as well as a number of references and citations not being entered correctly. In addition, concerns were raised regarding the present paper and the results and conclusion, namely in regards to the effect sizes used in the present study. In light of these errors the authors re-assessed and re-ran the whole analyses and the below corrections now apply: (1) Unfortunately, a few references were inserted wrongly and the mistakes occurred due to an old version of Endnote being used. The correct references are as follows: Pakravan H, Ahmadian M, Fani A, Aghaee D, Brumanad S, Pakzad B. The effects of melatonin in patients with nonalcoholic fatty liver disease: a randomized controlled trial. Adv Biomed Res. 2017;6:40. Grossman et al. [20] and Agahi et al. [21] are correct in Table 1.
