For each cluster (individual device type), bars show weighted prevalence estimates of individual flavor types reported among current exclusive users of flavored e-cigarettes. Use of fruit, menthol, or some other flavor significantly differed by device types (χ2 test P < .05).
aResults not shown because of statistically unreliable estimates (unweighted denominator <50 or relative SE >30%). Estimates for mod systems, those who reported “I don’t know the type” for device type and the flavor types “chocolate” and “clove or spice” are also not shown because of statistically unreliable estimates.
