However, in successive models of Model 3 and 4 (addition of POAG established and suspected risk factors), and Model 5 (further adjust for co-morbidities), we observed that while no metabolite exhibited significance at the NEF < 0.2 level (except for LPC(16:0) in Model 3), all were nominally significant and the direction of associations for the metabolites was similar ( p < 0.05).
