Relationship between simvastatin dose and mortality

	n	B	SE	OR	(95% CI)	p-value
Simvastatin dose
10 mg	15	4.346	0.825	77.189	(15.331–388.634)	<0.001
20 mg	76	3.019	0.351	20.472	(10.285–40.747)	<0.001
40 mg	352
80 mg	36	–1.003	1.054	0.367	(0.046–2.893)	0.341

Relationship assessed by logistic regression and adjusted for age and disease severity (CURB-65 score). To assess the effect on mortality of increasing doses of simvastatin, patients taking 10 mg, 20 mg and 80 mg were compared to those on 40 mg.

B = regression coefficient; CI = confidence interval; OR = odds ratio; SE = standard error
