Data
Patients’ age, gender, COVID-19 PCR test result, comorbid diseases,
intubation status, the day of the intensive care hospitalization,
laboratory values during hospitalization in the intensive care unit,
white blood cell (WBC), hematocrit (Hct), thrombocyte (Plt), neutrophil,
lymphocyte, monocytes, red cell distribution of width (RDW), Mean
platelet volume (MPV), c-reactive protein (CRP), total bilirubin,
albumin, aspartate aminotransferase (AST), alanine aminotransferase
(ALT) values, lactate dehydrogenase (LDH), blood groups, procalcitonin,
ferritin, fibrinogen, calcium (Ca), albumin, INR, blood gas parameters
(Ph, PO2, PCO2, lactate) duration of stay in the intensive care unit
were recorded. In addition, neutrophil-lymphocyte ratio (NLR) and
platelet-lymphocyte ratio (PLR) values were calculated according to
laboratory values.
Statistical analysis: Statistical Package for the Social Sciences (SPSS
25 Inc., Chicago, IL, USA) computer software was used for the
biostatistical analyses. The data obtained from the participating
patients were expressed as mean, standard deviation values, and as a
percentage where necessary. The Kolmogorov Smirnov test was used to
examine the normal distribution of the data. Data with normal
distribution were analyzed by student t-test. Group analysis of
non-parametric data was performed with the Mann-Whitney U test. Logistic
regression test was used for univariate analysis and to calculate odds
ratios (OR) with 95% confidence interval (CI). Categorical groups were
compared with the chi-square test. Cut-off values were obtained by
receiver operating curve (ROC) analysis.
