Random forest model diagnostics for predicting presenting visual impairment (VI)

	Baseline Visual Impairment
Model Diagnostic	Affected or Worse Eye*	Affected or Better Eye*
	Estimate (95% CI)	Estimate (95% CI)
Misclassification	0.20 (0.17, 0.23)	0.17 (0.14, 0.20)
AUC	0.84 (0.81, 0.88)	0.88 (0.85, 0.91)
Sensitivity	0.70 (0.65, 0.76)	0.77 (0.72, 0.82)
Specificity	0.89 (0.85, 0.92)	0.88 (0.84, 0.91)
PPV	0.84 (0.79, 0.88)	0.83 (0.78, 0.88)
NPV	0.78 (0.74, 0.82)	0.83 (0.79, 0.87)

CI, Confidence Interval; AUC, Area Under the Curve; PPV, Positive Predictive Value; NPV, Negative Predictive Value

^*In patients with unilateral infections the affected eye was analyzed, in patients with bilateral infection analyses were performed separately by including either the better or worse eye
