Looking for predictive factors of clinical response to adsorptive granulocyte and monocyte apheresis in patients with ulcerative colitis: markers of response to GMA

Table 4 Sensitivity, specificity, area under the curve (AUC), and confidence interval (CI) in the determination of the predictive factors of clinical response to GMA in patients with active ulcerative colitis

Measurements	Cut-off value	Sensitivity (%)	Specificity (%)	AUC (95%CI)
Cumulative PSL dose up to the 1^st GMA session	<2735.5 mg	61	95	0.78 (0.62-0.94)
WBC at 1^st GMA session	<10160/μL	61	85	0.72 (0.56-0.89)
Interval between relapse and 1st GMA session	<49.5 days	50	95	0.76 (0.61-0.92)

GMA, granulocyte and monocte apheresis; PSL, prednisolone; WBC, white blood cell.
