Table 5

 Vibration perception threshold test results by triallate exposure category

Vibration test* All subjects Hired 1976–85 Hired >1985
No/low exposure High exposure p† No/low exposure High exposure p† No/low exposure High exposure p†
*Reported as vibration units.
†Two sided t test used to compare the unadjusted mean of the high exposure group with the unadjusted mean of the no/low exposure group; F test used to compare the adjusted mean of the high exposure group with the adjusted mean of the no/low exposure group.
‡Adjusted for age, gender, and height using analysis of covariance.
