Name	Structure	Female (ρ, p)	Male (ρ, p)
Eicosenoylcarnitine	C20:1	0.2828, 0.0121	0.3551, 8.55E-4
Eicosadienoylcarnitine	C20:2	0.1344, 0.2409	0.3693, 5.04E-4
Arachidylcarnitine	C20:0	0.3078, 6.11E-3	0.2397, 0.0271
Decadienoylcarnitine	C10:2	0.3194, 4.37E-3	0.2323, 0.0324
Hydroxystearoylcarnitine	C18OH	0.3455, 2.95E-3	0.1457, 0.1845
Decatrienoylcarnitine	C10:3	0.2456, 0.0330	0.2304, 0.0365

For the 6 acylcarnitines with the highest correlation with age in the whole population, correlation with age by gender was tested. Spearman’s ρ and p-value are shown for correlations in females and males.
