*The OR can be interpreted as a HR.35
†Adjusted for time varying age (five age categories), sex, region of residence (five regions) and calendar year at start of follow-up. We did not mutually adjust for other exposure variables due to expected colinearity.18
HAV, hand-arm-vibration; SIS, subacromial impingement syndrome.
