Letter to the editor regarding "Generalized anxiety disorder in urban China: Prevalence, awareness, and disease Burden" [J. Affect. Disord. 234 (2018) 89-96].

Highlights • We pointed out the erratum of recent paper by Yu et al., (2018) in Journal of Affective Disorders. • The unit of prevalence was mistakenly written as ‰ in Table 2 of Guo et al. (2016) and also the article of Yu et al. (2018). • The current and lifetime prevalence of GAD and prevalence by location should be 5.17‰, 4.66‰ and 4.56‰, respectively. [ABSTRACT FROM AUTHOR]
