Fig. 1: A comparison of the most important predictive baseline variables per classifier based on the sign-based consistency resulting from the inner cross-validation cycles.

Significant predictors overlapping across the models are presented only. Variables with a sign-based consistency * Pfdr log10 ≥ 1.36 are considered significant (dotted line reflects the significance threshold). EUFEST classifier = pooled non-linear cross-validated SVM model on EUFEST cohort. PSYSCAN classifier = pooled non-linear cross-validated SVM model on PSYSCAN cohort. Leave-site-out classifier = leave site-out inner pooled cross-validated SVM model on the merged dataset (sites that included < 10 participants were excluded).
