Comparison of biochemical parameters between normal sleepers and groups with insomnia

Hormones	Normal (n=17)	Paradoxical Insomnia (n=19)	Psychophysiological Insomnia (n=17)	P
ACTH	25.08(17.94)^a	28.28(13.82)^a	21.94(12.39)^a	0.40
Cortisol	134.09(51.11)^a	153.86(62.87)^a	133.40(39.32)^a	0.45

Statistical analysis for the equality of the mean values among the three groups was evaluated using ANCOVA adjusted by sex, age, and BMI (P<0.05). Means with the same superscript letters within a row were not significantly different (P>0.05).
