Formula 1: The formula constructed using the WEKA Linear
Regression Formula to estimate presence of Thoracic CT involvement in
patients
0.2537 * gender +0.0267 * age +-0.0001 * leukocyte +0.0001 * neutrophil
+0.0001 * lymphocyte+0.0031 * CRP +-0.0029 * PCT +-0.0003 * ferritin

creatine +-0.2005 * INR +0 * D-dimer +- 0.0868 *
The formula’s rate of success in estimating the presence of thoracic CT
involvement turned out to be 78.92%.
