Mediation model of T1 MDD severity predicting T3 executive function via T2 inflammation

	β (s.e.)
Regression slopes: all samples
T1 MDD severity → T3 executive function	−0.17* (0.09)
T1 MDD severity → T2 inflammation	0.03** (0.01)
T2 inflammation → T3 executive function	−2.55*** (0.53)
T1 MDD severity → T2 inflammation → T3 executive function	−0.08** (0.03)

CFI, confirmatory fit index; β, unstandardized regression weight estimate; MDD, major depressive disorder; RMSEA, root mean square error of approximation; s.e., standard error.

Model fit indices: χ²(25) = 47.95, p = .004, CFI = .97, RMSEA = .04.
