Hydroxychloroquine (HCQ) has been implicated in antiviral activity in vitro against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). However, there is still controversy about whether HCQ should be used for coronavirus disease 2019 (COVID-19) patients due to the conflicting results in different clinical trials. To systematically assess the benefits and harms of HCQ for the treatment of COVID-19. Data sources were systematically searched from Pubmed, Biorxiv, ChiCTR, Clinicalrials.gov , and the Cochrane library of RCTs for studies published from inception to June 1, 2020, to obtain any possible inclusion. This meta-analysis of inclusion criteria was directed on the basis of the Preferred Reporting Items for Systematic Review and Meta-analysis Protocols (PRISMA-P). Pooled studies by the title and abstract were screened and removed in the light of meta-analysis by two reviewers. Seven studies involving 851 participants with COVID-19 were eligible for analysis. There was no significant difference in RT-PCR negative conversion between HCQ group and standard treatment (ST) group (RR = 1.11, 95% CI = 0.77-1.59, P = 0.591). The rate of exacerbated pneumonia on chest CT in HCQ group was lower than that in ST group (RR = 0.44, 95% CI = 0.20-0.94, P = 0.035). There was no statistical difference in progressed illness between the HCQ group and the ST group (RR = 0.66, 95% CI = 0.18-2.43, P = 0.530). Death (RR = 1.92, 95% CI = 1.26-2.93, P = 0.003) was distinctly different in HCQ group compared with ST group in the treatment of COVID-19. Our meta-analysis demonstrated that there was no robust evidence to support prescribing HCQ as a treatment for COVID-19.
