Adjusted mean differences in the log₁₀ of NK function for depression in females and males stratified by age¹

Depression estimates by group	NK function
	Estimate (95% CI)		P-value
Female Age ≤ 9.3 years	0.00	−0.02, 0.02	0.91
Male Age ≤ 9.3 years	0.01	−0.01, 0.02	0.36
Female Age > 9.3 years	0.02	0.00, 0.04	0.02
Male Age > 9.3 years	−0.02	−0.03, 0.01	0.37

For each variable, the estimates correspond to the change in log10 NK cell function of 1-U increase.

¹Analyses were adjusted for child age, sex, parent psychiatric symptoms (BSI), income, and prior NK function.
