Cover Story: The COVID-19 pandemic necessitated rapid clinical tools to optimize healthcare resources. While molecular testing is the gold standard, delays and logistical hurdles limit its use during surges. This study introduces new computer-aided screening techniques leveraging six machine-learning algorithms—including random forests, neural networks, and support vector machines. By analyzing real-world clinical data such as demographics, vital signs, and comorbidities, the researchers developed a robust model for pre-diagnostic risk stratification. Utilizing variable importance metrics to identify 13 key predictors, the study demonstrates that kernel-based SVMs provide high predictive accuracy. This model offers a rapid, accessible screening solution for resource-constrained clinical settings. View this paper
