In the survival analysis, it was shown that patients with radiological scores higher than 15 had a significantly longer survival time than patients with lower scores. (HR 4.71, 95% CI 1.43-15.46)In our study, it was shown that the radiological scoring performed on Thorax HRCTs of COVID-19 patients was highly correlated with lymphopenia, D-dimer, ferritin, SPo2 levels, which are the most important prognostic parameters. In patients with COVID-19, radiological scores can help to show the prognosis and survival of the disease.FootnotesCite this article as: European Respiratory Journal 2021; 58: Suppl. 65, PA3646.This abstract was presented at the 2021 ERS International Congress, in session “Prediction of exacerbations in patients with COPD”.This is an ERS International Congress abstract.
