Figure 1 Association between hours of vigorous physical activity per week and fecundability, fitted by restricted cubic splines. The reference level for the fecundability ratio is 0 hours/week. The curves are adjusted for cycle number, age, partner's age, body mass index, alcohol consumption, pack-years of smoking, intercourse frequency, last method of contraception, and hours of moderate physical activity per week. There were five knot points located at 0.5, 1, 2, 3, and 4 h/wk.
