Study adherence of head and neck cancer survivors in a cruciferous and green leafy vegetable 12-week randomized clinical trial at a southeastern, Comprehensive Cancer Center between January 2015 – September 2016

	N (%)	N (%)		N (%)
	Total (N=23)	Control (N=12)		Experimental (N=11)
Adherence to weekly telephone sessions^a
Mean adherence	90.4	95		85.8
Mean experimental group adherence to weekly vegetable goals^a
Green Leafy Vegetables	-	-		74.4
Cruciferous Vegetables	-	-		67.2
Overall	-	-		70.8
Median experimental vs control group vegetable intake baseline vs week 2–12 (cups/week)^b
		Baseline	Follow-up	Baseline	Follow-up
Green Leafy Vegetables	-	0	2	0	3
Cruciferous Vegetables	-	0	0	0	3
Mean experimental group vegetable intake baseline vs week 2–12 (cups/week)^b
Green Leafy Vegetables	-	-		0	5.5
Cruciferous Vegetables	-	-		0	3.5

Adherence was measured as completion of the weekly telephone sessions (for both groups) and self-reported weekly CV and GLV intake for the experimental group, irrespective of goal intake

Adherence to weekly goals assessed using data collected from weekly recalls and 24-hour diet recalls
