Systematic review: factors associated with risk for and possible prevention of cognitive decline in later life
Plassman BL, Williams JW, Burke JR, Holsinger T, Benjamin S.. Annals of internal medicine, 2010-06-14
Topic: Risk, prevention and care in population studies
An overall rating of the quality of evidence was assigned by using the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) criteria. Current tobacco use, the apolipoprotein E epsilon4 genotype, and certain medical conditions were associated with increased risk. Conclusion Few potentially beneficial factors were identified from the evidence on risk or protective factors associated with cognitive decline, but the overall quality of the evidence was low.

How this study scored 67/100
Published in a leading specialty journal, and it is a systematic review of all the studies on the question. Scored zero for sample size, effect reported and studied in people 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 39 of the 58 points we could judge it on, which is 67 out of 100.
