RESULTS
The mean age of the 508 patients whose SARS-CoV-2 RT-PCR test turned out positive was 54 (19-99). Of these patients, 250 (49.2%) were female and 258 (50.8%) male.
Thoracic CT scans showed that lung involvement was absent in 93 of the patients, mild in 114, moderate in 115, and severe in 159 (Table 1).
The WEKA Linear Regression Formulas calculated using the laboratory values and demographic data (Formulas 1, 2, 3) and the J48 Decision Trees (Figures 1, 2, 3) are given below.
