Table 4 Impact of ever WS exposure on SGRQ and SF-36 scores independent of current smoking, comorbidity, airway obstruction, and CMH status at baseline

From: Wood smoke exposure affects lung aging, quality of life, and all-cause mortality in New Mexican smokers

  1. SF-36 the short form 36 health survey questionnaire, SGRQ St. George’s Respiratory questionnaire, WS woodsmoke
  2. aBasic model assessed the impact of ever WS exposure on SGRQ scores using linear mixed effects model or on SF-36 scores using generalized linear model
  3. bAlternative model added Charlson comorbidity score (≥ 1 versus 0), airway obstruction, and CMH at baseline into the basic model to assess the independent components of effects for ever WS exposure
