Wine grape pomace flour improves blood pressure, fasting glucose and protein damage in humans: a randomized controlled trial

Table 4 Oral glucose tolerance test, HOMA and glycosylated hemoglobin in groups at baseline and 16 weeks

	Experimental		Control
	Basal (0 weeks)	Final (16 weeks)	Basal (0 weeks)	Final (16 weeks)
Postprandial glycemia 120 min (mg/dL)	85.0 ± 28.9	89.1 ± 34.2	82.7 ± 19.1	83.7 ± 34.8
Fasting insulin (mg/dL)	12.5 ± 8.3	11.8 ± 8.9	10.3 ± 4.6	8.9 ± 4.4
Postprandial insulin 120 min (mg/dL)	67.1 ± 68.3	60.3 ± 59.6*	57.8 ± 57.0	77.0 ± 97.2*
HOMA	2.90 ± 2.05	2.65 ± 2.17	2.30 ± 1.10	1.93 ± 1.02
Glycosylated hemoglobin (%)	5.2 ± 0.3^a	5.5 ± 0.3^b	5.1 ± 0.3^a	5.3 ± 0.3^b

Values are mean ± SD. Student t-test for paired samples was used to analyze differences of means within groups. Student t-test for independent samples was used to analyze differences of means between groups. Means within a group with different superscript letters are significantly different; P < 0.05 paired t test
* Indicate statistically significant differences in the changes produced by the intervention between the groups (P < 0.05, paired t test)
