The alternative Thomas-plot: A new tool for effective anemia diagnostics.

Introduction: The Thomas-plot has proven to be a helpful tool to discriminate between different types of anemia. This plot combines the reticulocyte hemoglobin content (Ret-He) with the soluble transferrin receptor (sTfR)/log ferritin (fer) ratio. In this study, we designed an alternative Thomas-plot in which Ret-He is combined with the transferrin (Tf)/log ferritin ratio.

Chest CT for triage during COVID-19 on the emergency department: myth or truth?

Purpose: We aimed to investigate the diagnostic performance of chest CT compared with first RT-PCR results in adult patients suspected of COVID-19 infection in an ED setting. We also constructed a predictive machine learning model based on chest CT and additional data to improve the diagnostic accuracy of chest CT.

Methods: This study's cohort consisted of 319 patients who underwent chest CT and RT-PCR testing at the ED.
