Questions raised over hydroxychloroquine study which caused WHO to halt trials for Covid-19
Exclusive: Australian researchers query origin of data used for Lancet study, but stress there is no evidence drug is a safe or effective treatment
Questions have been raised by Australian infectious disease researchers about a study published in the Lancet which prompted the World Health Organization to halt global trials of the drug hydroxychloroquine to treat Covid-19.
The study published on Friday found Covid-19 patients who received the malaria drug were dying at higher rates and experiencing more heart-related complications than other virus patients. The large observational study analysed data from nearly 15,000 patients with Covid-19 who received the drug alone or in combination with antibiotics, comparing this data with 81,000 controls who did not receive the drug.
