Table 5 Multivariable logistic regression analysesa for point prevalence abstinence and 6-month continuous abstinence

From: Self-perceived ability to cope with stress and depressive mood without smoking predicts successful smoking cessation 12 months later in a quitline setting: a secondary analysis of a randomized trial

N = 214 Responders-only

  1. Variables shown in the table are the two self-perceived ability to cope variables and statistically significant variables
  2. aIncluded variables: gender, age, number of cigarettes/day, number of years of education, number of years smoked, smoking in the week before baseline, passive smoking, drug use, snus use, other support, likelihood of being smoke-free in 1 year, handle stress and depressive mood without smoking, and willingness to use pharmaceuticals
