Quartiles were created from the distribution of ratio scores between effort and reward. The highest quartile of the distribution was compared to the lowest quartile.
Each model is presented without intercepts and adjusted for age, smoking, education and occupational status.
Estimate is given for the regression coefficient, confidence interval (95%) and p-value.
