¹ Days per year x number of years

² Lifetime days x intensity score

³ Cumulative use from enrollment and two follow-up questionnaires

⁴ Adjusted for age at blood draw and: ^ametolachlor, ^balachlor, ^cmetalaxyl

⁵ Linear regression using log(RTL) and categorical pesticide use (never, low, medium, high)
