COVID-19: coronavirus disease-19, OR: odds ratio, CI: confidence interval, CRP: c-reactive protein, Hb: hemoglobin, MCV: mean corpuscular volume, MCH: mean corpuscular hemoglobin, MCHC: mean corpuscular hemoglobin cocentration, RDW: red cell distribution width, WBC: absolute count of leucocytes, NLR: neutrophil lymphocyte ratio, MLR: monocyte to lymphocyte ratio, PLR: platelet to lymphocyte ratio. Values are expressed as either OR at 95% CI for logistic regression or unstandardized regression coefficient (ß), unadjusted R² and F-value for linear regression.
