  1. aEstimated scale score excluding exposure after back-transformation and controlling for confounders
  2. b p-value of linear mixed models regressing the outcome measure on survey year. Models were adjusted for age
  3. cValues represent the results from linear mixed models including exposure variable. Beta values have been back-transformed to estimate the coefficient on the original scale
  4. dRepresents interaction term present in model
  5. eThe results are based on a composite measure that includes all forms of workplace health promotion [WHP] (i.e., policy, amenities, injury support, health risk assessment, physical activities, health education, stress/mental health)
