Observational studies

On July 3 we have screened 280 new records.

Several randomized trials were identified this week assessing the effect of Dexamethasone, Colchicine, Hydroxychloroquine, and Chloroquine in addition to a trial evaluating re-Opening of Training Facilities during the COVID-19 pandemic are available on our website. Observational studies assessing Ivermectine, Hydroxychlroquine, Methylprednisolone, steroids and Immunoglobulin are available as well. Risk of bias assessments of all included and analysed studies are published on our website.

Following the publication of an expression of concern by the Lancet (June 3, 2020) regarding the paper by Mandeep Mehra et al—Hydroxychloroquine or chloroquine with or without a macrolide for treatment of COVID-19: a multinational registry analysis, and the retraction by 3 of the authors (June 4, 2020), we decided to delete data related to this study from our website

The research mapping has been updated on June 23, 2020 with 49 new registered RCTs identified in the WHO ICTRP.
