Association between quartile of moderate to vigorous activity and semen quality parameters. Adjusted means are presented for the median abstinence time (70.6 hrs), race (white), smoking status (former or never smoker), BMI (24.6 kg/m2), recruitment period (2009), total calorie intake (2939 kcals/day), and TV watching (14 hrs/week). Adjusted means for motility were additionally adjusted for median time from semen collection to start of semen analysis (10.0 hours). Tests for trend were conducted across quartiles using a variable with the median activity level in each quartile as a continuous variable in the linear regression models.
