Association Between Clinical Symptoms and Inflammatory Markers in First-Episode Unmedicated Patients with Major Depressive Disorder.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Depression represents a serious psychiatric disorder globally, imposing significant burdens on patients'daily lives. Numerous hypotheses including the inflammatory hypothesis. Changes in inflammatory factors within the bodies of individuals with depression may represent a key biological mechanism. Multiple clinical investigations have demonstrated that pro-inflammatory cytokine levels in the peripheral blood of depressed patients are markedly higher than in healthy controls, with the degree of elevation in these inflammatory markers positively correlating with the severity of depressive symptoms. We shall examine changes in specific pro-inflammatory and anti-inflammatory factors. Method: We employed the enzyme-linked immunosorbent assay (ELISA) to detect inflammatory cytokine levels in subject's serum samples. Clinical symptoms were assessed using the Childhood Trauma Questionnaire (CTQ), the 17-item Hamilton Depression Rating Scale (HAMD-17), and the Quick Inventory of Depressive Symptomatology (Self-Rating) (QIDS-SR16). Results: Compared to the healthy group, the depression group exhibited a significantly higher IFN-γ and IL-17 (p<0.05) and lower IL-4, MCP-1, MIP-1β, and IL-8 (p<0.05). Serum IL-4 levels showed significant positive correlations with HAMD-17 score (p=0.03), QIDS-SR 16 scores (p=0.009). IL-17 level was positively correlated with the QIDS-SR16 score (p=0.04). Several markers showed significant discriminatory power. IL-4 demonstrated the highest AUC of 0.72 (P < 0.01), with a sensitivity of 87.10% and specificity of 51.61%, indicating a moderate predictive value for depression. Conclusion: The distinct inflammatory profile-characterized by elevated IFN-γ/IL-17 and reduced IL-4/MCP-1/IL-8/MIP-1β-in first-episode MDD patients underscores the role of immune imbalance in early depression pathophysiology. The strong association of IL-4 with symptom severity and its high sensitivity for disease identification highlight its potential as a valuable clinical biomarker. These findings support further investigation into immune-based stratification of MDD patients, which could pave the way for more personalized diagnostic and therapeutic strategies targeting specific inflammatory pathways".
