	Corticosterone	0.041	<0.001	0.114	0.008
Blue	Glucose	0.459	<0.001	0.154	0.602
	Insulin	0.609	<0.001	0.181	0.587
	Corticosterone	0.102	0.275	0.308	0.162
Green	Glucose	0.021	<0.001	0.001	0.027
	Insulin	0.428	<0.001	0.810	0.426
	Corticosterone	0.760	0.001	0.787	0.523
Red	Glucose	0.421	<0.001	0.172	0.603
	Insulin	0.375	<0.001	0.003	0.766
	Corticosterone	0.095	0.004	0.692	0.095

Treatment (wavelength), time (sample time) and interaction effects were determined using repeated measures two-way ANOVA

Glucose, insulin and corticosterone responses are reported for the glucose tolerance test in LAN conditions with four different wavelength spectra

The AUC column contains results of paired t test on the net AUC curve
