Impact of comorbid diabetes on the risk of mortality from Covid-19. Studies reporting morality outcomes [or composite of death, renal replacement therapy/haemodialysis, ventilation, intubation or use of vasopressor (Abu-Jamous et al., 2021)] are hazard ratios [HR (Zhang et al., 2020a; Barron et al., 2020; Ciceri et al., 2020; Yu et al., 2020; Zhou et al., 2020; Abu-Jamous et al., 2021)], odds ratios [OR (Guan W. J. et al., 2020; Wu J. et al., 2020; Chilimuri et al., 2020; Docherty et al., 2020; Kim et al., 2020; Lee et al., 2020; Liu et al., 2020; Petrilli et al., 2020; Shi et al., 2020; Xu et al., 2020; Yan et al., 2020; Zhu et al., 2020; Al-Salameh et al., 2021; Fox et al., 2021; Shang et al., 2021)], or relative risks [RR (Smith et al., 2020)] after stratification of populations for the presence or absence of diabetes are shown here. Diabetes was not stratified into types 1 and 2, except where stated.
