Notes. Ref = reference group. OR = odds ratio. LCI = Lower confidence interval. UCI = Upper confidence interval. MITSE = Motivation and intention to stop using e-cigarettes within the next three months. SUTS-E = Strength of urges to use e-cigarettes. Significant associations (p < .05) are highlighted in bold. Multivariable Models were run with one socioeconomic indicator at a time. Regardless of the socioeconomic indicator used, the results did not change significantly. * p < .05, ** p < .01, *** p < .001.
