Retraction notice to "Part II: a step-by-step guide to latent class analysis" [Journal of Clinical Epidemiology 148 (2022) 170-173].

This article has been retracted: please see Elsevier Policy on Article Withdrawal (https://www.elsevier.com/about/policies/article-withdrawal). This article has been retracted at the request of the Editors-in-Chief, and with the full cooperation of the authors of the article. The article used notable portions of text from papers previously published by Pratik Sinha, Carolyn S. Calfee and Kevin L. Delucchi in Crit Care Med 49(2021) e63-e79 (https://doi.org/10.1097/CCM.0000000000004710) and by Bridget E. Weller, Natasha K. Bowen and Sarah J. Faubert in J Black Psychol 46(2020) 287-311 (https://doi.org/10.1177/0095798420930932). While these two papers were cited in the original article, a reader brought to the Editors' attention areas of verbatim text overlap without clear attribution through the use of quotation marks. One of the conditions of submission of a paper for publication is that authors declare explicitly that their work is original and has not appeared in a publication elsewhere. Re-use of any text must be appropriately cited and made visible/transparent to the reader. The scientific community takes a very strong view on this matter. We apologize to readers of the journal that this was not detected ahead of publication. The article has been republished with an updated version with clear attribution of all text where appropriate.
