Table 1 Activity patterns in LD conditions

From: Characterization of locomotor activity circadian rhythms in athymic nude mice

		Nude	WT	P
		(mean ± SEM)	(mean ± SEM)
ψ (min)		8.7 ± 6.3	8.1 ± 3.1	ns
	Interval
%Area	ZT12-23	64.54 ± 3.43	65.68 ± 6.82	ns
	ZT23-3	12.37 ± 2.17	14.81 ± 4.00	ns
	ZT3-10	13.49 ± 1.69	10.22 ± 1.75	ns
	ZT10-12	8.11 ± 1.13	6.85 ± 1.71	ns

Phase angle (ψ, difference of activity onset with the time of lights off) and percentage of activity for each ZT interval over total activity were calculated (% Area, see methods for details). P values correspond to Student’s t test between nude (n = 9) and WT (n = 6) control mice. Data are expressed as mean ± SEM.
