Özet
OBJECTIVES: This study aims to determine the prognostic signifi cance of the lymphocyte/mean platelet volume ratio (LMR) in terms of the clinical course of the disease in patients with COVID-19. METHODS: Patients over 18 who were evaluated for COVID-19 during the period from April 1, to April 30, 2020 were retrospectively scanned. Patients with at least 1 positive PCR test result were as assigned to Group 1 while patients with negative test results were assigned to Group 2. The LMR ratio was calculated by dividing the lymphocyte value by that of MPV. The relationship between LMR, severity of patients’ CT fi ndings and 28-day mortality was evaluated. RESULTS: A total of 938 patients were included in the study. It was observed that the lymphocyte and LMR levels were signifi cantly different in those who died within 28 days (p < 0.001, p ≤ 0.001). In the ROC analysis for the LMR level, the area under the curve (AUC) was found to be 0.737 (95% CI 0.639‒0.834). When the cut-off value of LMR was 0.045, the sensitivity was found to be 99.0 % and specifi city was 15.2 %. CONCLUSION: LMR can be a guide in multiple cases of care provided to critical patients, as is the case in the COVID-19 pandemic and can be used in recognizing critical patients (Tab. 5, Fig. 1, Ref. 21).
