Data Resource Profile: the Children and Young People with Long COVID (CLoCk) Study.

The Children and Young People with Long COVID (CLoCk) study in England aims to understand the symptoms and prevalence of long COVID in children and young people. The study includes over 200,000 participants aged 11-17 who were tested for COVID-19 between September 2020 and March 2021. Participants completed follow-up questionnaires at different time points, providing information on their physical and mental health. The study provides valuable insights into the long-term effects of COVID-19 in children and young people. However, there were some limitations, such as a low response rate and potential selection bias. The dataset is available for further analysis and collaboration. [Extracted from the article]
