Exploratory Outcomes.

S7 Table reports the exploratory results of the linear regression models estimating the association between nitrate measures and birth outcomes. The exposure column indicates the nitrate exposure estimated in the model. All linear regression models adjusted for maternal and paternal characteristics, county-year fixed effects, and year-month fixed effects, and weighted for the difference between date of conception and date of nearest public water measure. Standard errors reported in parentheses. All exposures are modeled as binary. Gestational Age (weeks) and Birth weight (g = grams) and are continuous outcome variables. & Indicates that birthweight models adjust for gestational age. ^ Reported on a binary (0–1) scale. & Adjusts for gestational age. # p = 0.096.
