For IL-8 and IL-6 levels above LLOD we found no significant differences related to depression severity (assessed by HDRS-17 score > 24 vs ≤ 24), severity of co-morbid anxiety (assessed by HARS score > 20 vs ≤ 20) or related to suicidal ideation (yes/no) (Additional file 1: Table S9) neither for any of the significant secondary outcomes (Additional file 1: Table S10). The gene discussed is IL6; the disease is depressive symptom measurement.
