Cohort studies examining the association of statin treatment and AAA growth

			Growth rate (mm/year)
Ref	n	Initial AAA diameter	Statin users	Non statin users	Risk factors adjusted for in analyses
[13]	130	45	−0.5	4	No adjustment
[14]	150	38	AED −1.16 (95% CI, −1.99, −0.33)		Age, gender, initial AAA diameter, intermittent claudication, DM, COPD, NSAID prescription
[15]	121	39	1.9±1.8*	2.6±2.4*	No adjustment
[16]	147	41 (±8.0)	AED −1.2 (95% CI, −2.3, −.06)		Age, gender, initial AAA diameter, height, weight, DM, cerebral vascular disease, hypertension, creatinine clearance, hyperlipidaemia
[17]	213	40 (37–44)	1.6	2.5	No adjustment

^*difference in AAA growth rate not statistically significant (p>0.05); AED, adjusted estimated difference for statin use; COPD, chronic obstructive pulmonary disease.
