• Abstract summary: The dataset of the study consists of 38 routine blood values of 2597 patients who died (n = 233) and recovered (n = 2364) from COVID-19 in August-December, 2021. The most efficient binary combinations with procalcitonin were obtained with D-dimer, ESR, D.Bil and ferritin. In the HGB model operated with a single feature, the most efficient features were Procalcitonin (F12 = 0.96) and ferritin (F12 = 0.91)

• Abstract: Early evaluation of patients who require special care and high death expectancy in COVID-19 and effective determination of relevant biomarkers on large sample groups are important to reduce mortality. This study aimed to reveal the routine blood value predictors of COVID-19 mortality and to determine the lethal risk levels of these predictors during the disease process. The dataset of the study consists of 38 routine blood values of 2597 patients who died (n = 233) and recovered (n = 2364) from COVID-19 in August-December, 2021. In this study, histogram-based gradient boosting (HGB) model was the most successful mashine learning classifier in detecting living and deceased COVID-19 patients (with squared F1 metrics F1^2 = 1). The most efficient binary combinations with procalcitonin were obtained with D-dimer, ESR, D.Bil and ferritin. The HGB model operated with these couples correctly detected almost all of the patients who survived and died. (precision > 0.98, recall > 0.98, F1^2 > 0.98). Furthermore, in the HGB model operated with a single feature, the most efficient features were Procalcitonin (F1^2 = 0.96) and ferritin (F1^2 = 0.91). In addition, according to the two-threshold approach ferritin values between 376.2 mkg/L and 396.0 mkg/L (F1^2 = 0.91) and procalcitonin values between 0.2 mkg/L and 5.2 mkg/L (F1^2 = 0.95) were found to be fatal risk levels for COVID-19. Considering all the results, we suggest that many features combined with these features, especially procalcitonin and ferritin, operated with the HGB model, can be used to achieve very successful results in the classification of those who live and die from COVID-19.Moreover, we strongly recommend that clinicians consider the critical levels we have found for procalcitonin and ferritin properties to reduce the lethality of COVID-19 disease.

  Deep learning (DL) classification models were trained to identify COVID-19-positive patients on 3D computed tomography (CT) datasets from different countries. We trained nine identical DL-based classification models by using combinations of the datasets with a 72% train, 8% validation, and 20% test data split. The models trained on multiple datasets and evaluated on a test set from one of the datasets used for training performed better.

  We reported an explainable, intuitive, and accurate machine learning model based on logistic regression to predict the fatality rate of COVID-19 patients. We found that when the fatality probability produced by the logistic regression model was over 0.8, the model had the optimal performance in that it was able to predict patient fatalities more than 11.30 days on average with maximally 34.91 days in advance. Such a model can be used to identify COVID-19 patients with high risks with three blood biomarkers and help the medical systems around the world plan critical medical resources amid this pandemic.
