Conclusion: Identified prognostic factors (threshold leukocyte ≥ 11.6 k / μl, platelets 191 k / μl, D-dimer ≥ 1164 ng / ml, ferritin ≥ 370.73 ng / ml, CRP ≥ 26 mg / l, blood glucose > 7.47 mmol / l) can help clinicians and policy makers in tailoring management strategies for patients with COVID-19 infectious disease while researchers can utilise our findings to develop multivariable prognostic models that could eventually facilitate decision-making and improve patient important outcomes.
