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
Post-operative cognitive decline (POCD) is characterized by impairments in cognitive functions. Coronary artery bypass grafting (CABG) is associated with a high risk of POCD due to its impact on neuroinflammation and oxidative stress. In this study, we investigated the dynamics of neurotrophic, inflammatory, and oxidative stress markers in a cohort of post-CABG patients to identify potential biomarkers for POCD. Blood samples were collected at baseline (immediately post-surgery) and at 3-month follow-up. Expression levels of NRF2 and other regulators of oxidative stress (GST, GSS, HMOX1, CAT, HSP27, and LOX-1), inflammatory mediators (IL-6, IP-10, and NFκB), and neuroprotective factor (BDNF) were analyzed. Cognitive assessments were performed using RBANS, TMT, TIB and MMSE. POCD patients exhibited an initial upregulation of NRF2-related antioxidant genes, which failed to sustain at 3-months follow-up, leading to a decline in HMOX1, IP-10 and BDNF protein levels, along with increased LOX-1 protein level and NFκB expression, indicating persistent oxidative stress and inflammation. In contrast, non-POCD patients demonstrated a sustained increase in antioxidant and neuroprotective markers, suggesting a more effective compensatory response. ROC analysis identified HMOX1 and BDNF as significant predictors of POCD, with LOX-1 and IP-10 emerging as diagnostic markers at follow-up. In conclusion, our findings highlight the dynamic regulation of oxidative stress and inflammatory pathways in POCD, emphasizing the failure of sustained neuroprotection in affected patients. Further large-scale studies are necessary to validate these findings, and biomarker-based screening could facilitate early risk stratification and targeted interventions to improve cognitive outcomes after cardiac surgery.
