Correlation of gastric emptying scintigraphy at 2 h and 4 h and gastric emptying time together with sensitivity and specificity values (n = 125).

Gastric emptying parameter	SP–GET correlation (95% CI)	Sensitivity	Specificity	AUC (95% CI)
GES 2 h	0.63 (0.50–0.75)	0.34	0.93	0.79 (0.71–0.88)
GES 4 h	0.73 (0.61–0.82)	0.44	0.93	0.82 (0.77–0.91)
GET	NA	0.65	0.87	0.83 (0.74–0.90)
