Sex and Race Differences in the Association Between Statin Use and the Incidence of Alzheimer Disease
Zissimopoulos JM, Barthold D, Brinton RD, Joyce G.. JAMA neurology, 2017-02-01
Topic: Drug trials: efficacy and safety
However, several drugs prescribed for other conditions have been associated with reducing its risk. Results The 399 979 study participants included 7794 (1.95%) black men, 24 484 (6.12%) black women, 11 200 (2.80%) Hispanic men, 21 458 (5.36%) Hispanic women, 115 059 (28.77%) white men, and 195 181 (48.80%) white women. High exposure to statins was associated with a lower risk of Alzheimer disease diagnosis for women (hazard ratio [HR], 0.85; 95% CI, 0.82-0.89; P<.001) and men (HR, 0.88; 95% CI, 0.83-0.93; P<.001). Simvastatin was associated with lower Alzheimer disease risk for white women (HR, 0.86; 95% CI, 0.81-0.92; P<.001), white men (HR, 0.90; 95% CI, 0.82-0.99; P=.02), Hispanic women (HR, 0.82; 95% CI, 0.68-0.99; P=.04), Hispanic men (HR, 0.67; 95% CI, 0.50-0.91; P=.01), and black women (HR, 0.78; 95% CI, 0.66-0.93; P=.005). Atorvastatin was associated with a reduced risk of incident Alzheimer disease diagnosis for white women (HR, 0.84, 95% CI, 0.78-0.89), black women (HR, 0.81, 95% CI, 0.67-0.98), and Hispanic men (HR, 0.61, 95% CI, 0.42-0.89) and women (HR, 0.76, 95% CI, 0.60-0.97). Pravastatin and rosuvastatin were associated with reduced Alzheimer disease risk for white women only (HR, 0.82, 95% CI, 0.70-0.95 and HR, 0.81, 95% CI, 0.67-0.98, respectively). High statin exposure was not associated with a statistically significant lower Alzheimer disease risk among black men. Clinical trials that include racial and ethnic groups need to confirm these findings.

How this study scored 55/100
Published in a leading specialty journal. Scored zero for study design and randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multi-centre collaboration, so those were left out: it earned 32 of the 58 points we could judge it on, which is 55 out of 100.
