Similar patterns of association were observed for: b SOC 171 and 1719; c SOC 474 and 4743; d SOC 615, 6151, and 6158. *P-value <0.05. P-trends <0.05 for duration (Never, <5 years, 5+ years) of employment are bolded. Results presented for a posteriori high- and low-risk occupations only if we observed (1) a significant association with ever employment or (2) both a significant association with duration of employment and P-value for ever employment of 0.10 or lower. Results presented if a job was held by >10 participants.
