M = Manual; NM = Non Manual.
Low frequency of use: ≤1 time per week; Mid/high frequency of use: >1 time per week.
OR: Odd Ratio; OR = 1 denotes reference category.
OR1: Odds Ratio of low frequency use vs. no use.
OR2: Odds Ratio of mid/high frequency use vs. no use.
Adjusted OR*: OR adjusted for potential confounders: in the case of gender by age, social class and level of education. Fagerström test was adjusted for all other variables.
P-value derived from the Wald test.
