  1. Four thousand five hundred sixty-seven workers with self-reported neck or upper back pain by gender and age group. Mean number of n-days for description only. P values indicate the difference in distribution of absence days between reporting high or low exposure. Wilcoxon Rank Sum Test * = two tailed; bold numbers indicate a statistically significant difference. N = number of workers
