The effect size (prevalence rates of anxiety) and a 95% CI for each paper will also be calculated. The heterogeneity of the studies will be assessed using the I 2 statistic. The risk of bias in individual studies will be assessed using the STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) checklist.
This paper presents the protocol for a meta-analysis with the following two aims: (1) to examine the prevalence of anxiety among health care workers and determine whether it has increased due to the COVID-19 pandemic, and (2) to investigate whether there has been an increase in publication bias.Īll related studies that were published/released from 2015 to 2020 will be searched in electronic databases (Web of Science, PubMed, PsyArXiv, and medRxiv). In addition, publication bias and low-quality publications have become widespread, which can result in the dissemination of unreliable findings. The COVID-19 pandemic has been declared a public health emergency of international concern this has caused excessive anxiety among health care workers.
