Type of Finding	Category	SSLR	AUC
Diagnosis	Σ+	1.6 (1.3–2.1)	0.64 (0.58–0.70)
	Σ−	0.49 (0.35–0.67)
GCCT score	92–100	0.045 (0.0076–0.15)	0.95 (0.91–0.97)
	82–90	0.13 (0.065–0.23)
	72–80	1.5 (0.83–2.8)
	62–70	55 (9.5–4300)
	≤60	5000 (130–10⁹)
Disclosure response	DR = no	10⁶ (41–10¹⁴)	0.73 (0.68–0.78)
	DR = other	5.2 (2.5–12)
	DR = yes	0.52 (0.42–0.63)

Data are median stratum–specific likelihood ratio (SSLR) and area under the ROC curve (AUC), with 95% confidence intervals. SSLRs and AUCs are rounded to two significant digits. Σ+, diagnosis of schizophrenia or schizoaffective disorder; Σ−, other diagnoses.
