Bold values indicate statistically significant p < 0.05

*p-value indicating (1) p-value for the overall effect the specific scale has on risk of a first CHD (coronary heart disease) event for scales with more than two categories, and (2) p-value for the dummies when compared to the reference category, i.e. t3 compared to t1

^aAdjusted for age and sex

^bAdjusted for age, sex and reporting at least one disease and/or neck/back pain

^cTertile 1 (t1) versus tertile 3 (t3). Differences between t1 and t2 were not significant and therefore not presented in the table
