Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Diagnostic accuracy of the index test (explaibable AI system EDDA) on the diagnosis of malignant (invasive melanoma and non-invasive melanomas (melanoma in-situ and lentigo maligna)) and benign (nevus) lesions. Malignant and benign lesions are present in the data set at a ratio of 1:1. The diagnostic accuracy is measured by * Accuracy * Sensitivity * Specificity * Area under the receiver-operator curve (AUROC) * Area under the precision-recall curve (AUPRC) With the majority vote of the pathologist panel serving as reference standard. | — |
Secondary
| Measure | Time frame |
|---|---|
| Diagnostic accuracy of EDDA on the differential diagnosis of invasive melanoma, non-invasive melanoma (NIM; here: melanoma in-situ and lentigo maligna) and nevus. The diagnostic classes are present in a ratio of 3:1:4 (invasive melanoma:NIM:nevus) in the dataset. Due to the number of classes and/or class imbalances, the diagnostic accuracy for the outcomes of the secondary endpoint are measures as follows: * Accuracy * Class-balanced accuracy * F1-score * Sensitivity (using a one-against-all-approach) * Specificity (using a one-against-all-approach) * Area under the receiver-operator curve (AUROC) (calculated per class) * Area under the precision-recall curve (AUPRC) (calculated per class) With the majority vote of the pathologist panel serving as reference standard. | — |
