ROC curves for low opacity and high opacity percentages. Separated ROC curves are generated for the left lung (blue), the right lung (red), and both lungs combined (green). The value of LOP, provided by the AI software, uses the presence of ground glass opacity, provided by the radiological report, as ground truth, while the value of HOP, provided by the AI software, uses the presence of consolidation, provided by the radiological report, as ground truth. LOP: low opacity percentage; HOP: high opacity percentage
