eVDV, estimated vibration dose value from all occupational sources combined in past week.
*In an average working day.
The PRs used to derive attributable numbers were mutually adjusted and adjusted also for age (classified as in table 1), height (in five bands), current smoking, frequent headaches, frequent tiredness, or stress. Estimates have been rounded to the nearest hundred. Bootstrapped 95% CIs were based on 200 resampling iterations.
