Table 3 Adjusted R2 Values and Significance of Linear Regression Model to Assess the Contribution of TNF-α, MIF, and IL-1β, Alone or in Combination, in Predicting the Treatment Response in the Whole Sample, in the Escitalopram-Treated Group and in the Nortriptyline-Treated Group

From: Candidate Genes Expression Profile Associated with Antidepressants Response in the GENDEP Study: Differentiating between Baseline ‘Predictors’ and Longitudinal ‘Targets’

 

Whole sample ( n =74)
