study finds not causal link
Many previous studies have found a correlation between smoking and dementia. However, Erin Abner of the University of Kentucky's Sanders-Brown Center on Aging (SBCoA) and colleagues wanted to explore outcomes using a different method of data analysis.
"The underlying data (in those studies) was solid, but the analysis didn't take into account the idea of competing risk of mortality, which we felt was an important factor to consider in this case since smoking is so strongly associated with earlier death," Abner said.
