ANCOVA of individual markers for oxidative stress. For the 3 markers that showed a significant group difference between the control and HypAll, an ANCOVA was performed. The corrected coefficient of determination (R²), the number of cases (n), and the significance (p) of the model, as well as the significance of the factor group (control vs. HypAll) and the covariate age, are given.

	R2	n	p (Model)	p (Group)	p (Age)
SHp	0.31	57	<0.001	0.043	<0.001
3-Nitrotyrosine	0.35	65	<0.001	<0.001	0.148
15-F2t-isoprostane	0.26	34	0.003	0.087	0.008

SHp = free thiol groups in proteins.
