After taking into account the sex-specific effect on glycine, the genetic glycine-CHD association based on CPS1 only did also not differ by sex (women: OR [95% CI] = 0.96 [0.91,1.00], men: OR [95% CI] = 0.94 [0.85,1.03], psex = 0.74). This evidence concerns the gene CPS1 and coronary artery disorder.
