Association between female (a) and male (b) sugar-sweetened soda intake and fecundability, fitted by restricted cubic splines, PRESTO, 2013–2017. The reference level for the FR is 0 sugar-sweetened sodas/week. The curve for female sugar-sweetened soda intake and fecundability is adjusted for female age, race/ethnicity, education, income, smoking history, BMI, physical activity, caffeine intake, sleep duration, PSS-10 score, intercourse frequency, and doing something to improve chances of conception. The curve for male sugar-sweetened soda intake and fecundability is adjusted for male and female age, male race/ethnicity, male and female BMI, education, income, and smoking. The splines are trimmed at the 99th percentile and have three knots at 2, 5, and 10 sugar-sweetened sodas/week.
