  1. aData missing from two carpenters due lack of hand diagram, and data excluded from two painters due to debut of white fingers before age 18
  2. bExcluding participants with diabetes, cardiovascular, thyroid or rheumatic disease, impaired perception of vibration in the foot, or peripheral nerve entrapment in upper extremity/neck (except for carpal tunnel syndrome)
