Abstract

This cross-sectional study estimates the prevalence of electronic cigarette use among actively smoking stroke survivors in the US and evaluates its association with at least 1 cigarette-smoking cessation attempt in the past year.

How strong is the evidence?

Evidence Hub reads this as a cross-sectional, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause.
