PPARγ as a predictive biomarker for antidepressant response in major depressive disorder: Insights from TNIP1 transcriptional regulation.

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
Introduction: Major depressive disorder (MDD) is a debilitating disease possibly linked to immune defense mechanisms. TNIP1, a key anti-inflammatory regulator in NF-κB and TLR pathways, is implicated in MDD, but its transcriptional regulation and role in treatment response are unclear. Methods: We analyzed mRNA expression of TNIP1 and 13 transcription factors in monocytes from pre- and post-treatment (4-6 weeks) MDD patients and healthy controls. Peripheral blood mononuclear cells were isolated, tagged by CD14, and mRNA was extracted and analyzed. Participants were recruited at Kaohsiung Chang Gung Memorial Hospital (2014-2025). ANCOVA, paired t-tests, and multiple linear regression adjusted for age, gender, BMI, and smoking were used to compare groups and predict treatment outcomes. Results: This study encompassed 62 MDD patients and 52 healthy controls. Pre-treatment HAMD-17 averaged 23.90 ± 4.60, and post-treatment HAMD-17 averaged 8.43 ± 4.24. MDD patients showed higher PPAR-γ ( Conclusion: This study highlights the differential expression of PPAR-γ, FOS, and JUN in MDD patients, underscoring their potential roles in immune regulation. The association between lower pre-treatment PPAR-γ expression and improved treatment outcomes suggests its utility as a biomarker for predicting therapeutic response.
