Table 2. Frequency of CD8⁺ T lymphocytes in obese children with or without metabolic syndrome.

EM CD8+ T cell (n=47)	Metabolic syndrome
	Negative (n=15)	Positive (n=32)	p-value*
IL-7Rαlow	48.4±11.5%	60.1±19.1%	0.047
IL-7Rαlow CX3CR1+	41.5±11.9%	53.8±20.1%	0.036
IL-7Rαhigh CX3CR1−	46.5±12.3%	35.3±17.8%	0.028

Values are presented as mean±standard deviation.

CD8⁺ T cells are cytotoxic T cells that include IL-7Rα^low/CX3CR1⁺ and IL-7Rα^high/CX3CR1^– effector memory (EM) T cells.

IL-7Rα: interleukin-7 receptor-alpha.
