In the article by Doi et al. (2021)
, in the section 2.5, the sentence “Serum 25(OH)D levels were determined through chemiluminescent immunoassay (DiaSorin Inc)” should read as follows:Serum 25(OH)D levels were determined through electrochemiluminescence immunoassay (Roche Diagnostic GmBH).We apologize for this error.
