  • AUC on validation and test set figures describe the performance of each model on predicting the probability of symptomatic AD diagnosis for each individual eye in the independent validation set. AUC values represent average performance over epochs 50–100. An ‘x’ indicates that the input(s) were included in the model described in that row.

  • *Indicates best-performing model.

  • AD, Alzheimer’s disease; AUC, area under the receiver operating characteristic curve; FAF, fundus autofluorescence; GC-IPL, ganglion cell-inner plexiform layer thickness maps; OCTA, optical coherence tomography angiography; UWF, ultra-widefield color images.
