  1. Each model was evaluated based on three independent validation datasets: Zhou 2020, Xiong 2023, and Mathys 2024, using the same eigengene thresholds identified in the discovery cohort. Accuracy, sensitivity, and specificity were calculated by comparing the model’s predictions to ground-truth labels derived from eigengene expression thresholds. On each row, the genes in the “Removed” column are excluded, leading to the selection of the pair of genes in the “Selected” column.
