Table 8. Sleep Problems Predict Aggression in Men on Simvastatin and Combined Statins.

	Change in Sleep Problems			Baseline Sleep Problems
	Beta ± SE	95% CI	P	Beta ± SE	95% CI	P
On Placebo N = 188	0.39 ± 0.50	-0.59, 1.4	0.43	-0.16 ± 0.12	-0.39, 0.068	0.17
On Pravastatin N = 179	0.21 ± 0.62	-1.0, 1.4	0.74	0.082 ± 0.13	-0.17, 0.34	0.53
On Statins N = 363	2.2 ± 0.55	1.1, 3.3	<0.001	0.23 ± 0.13	-0.035, 0.49	0.089
On Simvastatin N = 184	3.3 ± 0.83	1.7, 4.9	<0.001	0.38 ± 0.23	-0.068, 0.83	0.096

Beta = regression coefficient; CI = confidence interval; SE = standard error. Regression analysis assessing prediction of change in aggression by self-rating of change in sleep problems, stratified by treatment arm, adjusted for baseline and change in sleep problems; and baseline aggression (Overt-Aggression-Scale-Modified–Aggression-Subscale).
