Cross validated syndrome classification results using different facial representations and classifier models.

Facial Representation	Model	Mean Top-1 Sensitivity (%)	Mean Top-3 Sensitivity (%)
3D Surface	PCA + MLP	40.7 (0.9)	61.6 (2.1)
2D Color	ArcFace + MLP	34.2 (0.9)	53.0 (1.4)
2D Color	CNN	32.6 (1.1)	53.4 (1.7)
2D Colorless	CNN	26.3 (3.2)	46.6 (3.7)
Depth	CNN	24.8 (2.9)	42.1 (4.7)

Top-1 and top-3 syndrome sensitivity scores were averaged across the 43 syndrome classes. Standard deviations across cross validation folds are shown in parentheses.
