Linear regression analysis at first visit	controls	rs58854276/A	−0.1	1.0	0.89
Linear regression analysis at first visit	controls	rs3828599/A	0.2	1.2	0.89
Repeated-measures linear mixed model	cases	rs58854276/A	−2.1	1.3	0.053

First visit refers to the time of blood sampling for controls. In all analyses, sex was used as a covariate.
