Adjusted models account for average relative humidity (continuous) and PM2.5 exposure (continuous) in same time period prior to AFC, age (continuous), education (<college vs. ≥college), smoking status (ever vs. never), year of AFC (continuous), month of AFC (Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, Dec), and diagnosis of diminished ovarian reserve and ovulation disorders.
