In acute NAION, there were eight molecules that were distinct from age-matched controls (unadjusted P < 0.05, permutation test). In chronic NAION, there were 15 molecules that were distinct from controls (P < 0.05 for status effect in multiple linear regression. C-X-C motif chemokine ligand 10 (CXCL10) and interleukin-1α (IL-1α) had the smallest P values in Bonferroni test (top of the chronic list). Three proteins were common to acute and chronic NAION (italicized).
Delta, average over controls subtracted from the average over chronic cases; P, fraction of permutation tests that have delta at least as large as the observed delta; Estimate, linear regression coefficient; SE, standard error of the estimate; T, estimate/SE; p: P value of linear regression; p. bonf: P value of Bonferroni test.
