Multivariate linear regression analysis of factors associated with plasma IGF1

Plasma characteristics	β coefficient (S.E.)	P value
Neurocognitive impairment	−8.48 (10.45)	0.418
Gender, male	31.81 (15.2)	0.039
Age	−1.31 (0.61)	0.033
AIDS	−18.91 (10.74)	0.081
AST	−0.36 (0.16)	0.026

β coefficients less than zero indicate an inverse association between the characteristic and plasma IGF1.
