To the Editor We read the published study by Garrido-Miguel et al, “Prevalence and Trends of Overweight and Obesity in European Children from 1999 to 2016: a Systematic Review and Meta-analysis,”1 carefully. However, we found some points worth discussing in the article.
First, according to requirements of Preferred Reporting Items for Systematic Reviews and Meta-Analyses,2 detailed retrieval strategies should be provided in the article. But we did not find it in this article. Therefore, we cannot repeat the authors’ meta-analysis.
