This article is a Preprint
Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
Background During the current Coronavirus Disease 2019 (COVID-19) pandemic, diabetic patients face disproportionately more. Anti-inflammatory effects of hypoglycemic agents have been reported, and their beneficial or harmful effects in patients with diabetes and COVID-19 remain controversial. Purpose This study was performed to clarify this association. Data Sources Relevant literature was searched on China National Knowledge Infrastructure (CNKI), Wanfang Data Knowledge Service Platform, Chinese periodical service platform VIP Database, Sinomed (China Biology Medicine, CBM), MedRxiv, PubMed, ScienceDirect, Web of Science, Ovid Databases (LWW), Springer Link, Wiley Online Library, Oxford Academic, Nature Press Group, Cochrane Library and BMJ Evidence-Based Medicine up to November 14, 2020. Study Selection Only observational studies of hypoglycemic agents vs. drugs or therapy without hypoglycemic agents in adult diabetic patients with COVID-19 were included. Data Extraction Data of death and poor composite outcomes were extracted. Data Synthesis The pooled effects were calculated using the fixed-effects or random-effects models based on heterogeneity assessment. Limitation Most studies were retrospective cohort studies with relative weak capability to verify causality. Conclusion Home use of metformin might be beneficial in decreasing mortality in diabetic patients infected with SARS-CoV-2. There is insufficient evidence to conclude that metformin and other hypoglycemic agents are associated with poor composite outcomes. More prospective studies, especially RCTs are needed.
