Association between polygenic risk scores and longitudinal changes in lipid levels over 3 years in adolescents (n = 620)

Polygenic risk score	Lipid trait	Lipid traits at baseline (n = 620)			Lipid traits at follow-up (n = 620)			Three-year changes in lipid traits (n = 620)

Lipid traits at baseline and follow-up were natural log (ln) transformed. The 3-year changes in lipid traits were transformed as ln(Y + 1). ^a P values were obtained from linear regression with the adjustment for principal components, sex, age at baseline, and BMI at baseline. ^b P values were obtained from linear regression with the adjustment for principal components, sex, age at follow-up, and BMI at baseline and follow-up. ^c P values were obtained from linear regression with the adjustment for principal components, sex, age at follow-up, BMI at baseline and follow-up, and lipid trait at baseline
