Implication and recommendation:
This meta-analysis suggests a strong association between risk factors
(mortality and co-morbidities) with DM COVID-19 infected patients. To
reduce risk of disease progression, preventive measures should be
considered by DM patients. Proper management of blood glucose level
during COVID-19 pandemic might help DM patients to avoid humanistic and
economic burden which may arises due to ICU admission, frequent hospital
visits, hospitalization and mechanical ventilation requirement.
Conclusion
This meta-analysis of observational study showed a significant
association between mortality and DM COVID-19 infected patients. Other
co-morbidities especially CVD/hypertension could be a serious threat for
DM COVID-19 infected patients for the higher mortality. Further long
term, multinational and large sample size clinical studies warranted to
justify current findings.
