Markers of inflammation by age group

Variables	Adults n = 100	Older adults n = 133	p value
IL-1 ($\mu g/mL$)	14.3 (8.7 – 15.6)	9.19 (7.2 – 10.8)	< 0.001
IL-6 ($\mu g/mL$)	6.46 (5.67 – 7.85)	7.39 (5.02 – 9.42)	0.455
IL-8 ($\mu g/mL$)	16.9 (13.7 – 26.9)	15.8 (12.3 – 40.4)	0.742
IL-10 ($\mu g/mL$)	4.04 (3.47 – 4.32)	3.90 (1.57 – 4.91)	0.582
TNF-α ($\mu g/mL$)	6.08 (4.87 – 6.48)	6.29 (2.78 – 8.53)	0.195

Abbrevion: IL: Interleukin; TNF-α: Tumor necrosis factor alpha. Data are presented as mean ± SD and median (p25 – p75). Adults correspond to the group from 45 to 59 years old and Older adults to the group from 60 to 74 years old. For comparison, Student's t was used for normal data and Mann–Whitney U for non-parametric data. p < 0.05 is considered significant
