Neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, and absolute lymphocyte count as mortality predictor of patients with Coronavirus Disease 2019

INTRODUCTIONCoronavirus Disease 2019 (COVID-19) has a various spectrum of symptomsfrom asymptomatic to severe. Inprevious research, hematological examination could predict the severity of the infection. This study is aimed to evaluate Neutrophil-to-Lymphocyte Ratio (NLR), Platelet-to-Lymphocyte Ratio (PLR), and Absolute Lymphocyte Count (ALC) as a predictor of COVID-19 mortality. MATERIALS AND METHODSThe study was a cross sectional research with retrospective design by collecting data from medical records of the COVID-19 patients at a General Hospital Anwar Medika of East Java, for the period June 2020 to January 2021. A comparative test was performed using the Mann-Whitney test. The predictive ability was assessed using the ROC curve. RESULTSA total of 70 subjects were involved in this study with 16 (22.9%) mortality. And the average NLR and PLR were 4.11 and 174.39. The Mann-Whitney test showed significant results (p
