TABLE 3.

Multivariate linear regression analyses between PAG and 8‐OHdG, and skin autofluorescence (SAF), adjusted for age, sex and presence of DM.

	8‐OHdG		SAF
	Standardised beta	p‐value	Standardised beta	p‐value
Age	0.385	.005	0.403	<.001
Sex	0.009	.947	−0.132	.117
Presence of DM	−0.125	.398	0.161	.071
PAG	0.294	.047	0.165	.062

Note: A multivariate model was calculated only for correlations for which a significant univariate correlation was found (Figure 5). Non‐normally distributed variables were log10 transformed prior to analysis. Standardised β coefficients and p‐values are given for each model. Significant associations (p < .05) are depicted in bold.

Abbreviations: 8‐OHdG, 8‐hydroxydeoxyguanosine; DM, diabetes mellitus; PAG, phenylacetylglutamine; SAF, skin autofluorescence.
