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.

Abstract
Persistent fear responses and impaired fear extinction are characteristic features of stress-related disorders. Dopaminergic signalling within amygdala-centred circuits contributes to fear extinction, but the associated molecular mechanisms remain unclear. Here, we investigated whether selective dopamine transporter (DAT) inhibition with CE-123 (10 mg/kg, intraperitoneally) facilitates fear extinction and induces region-specific molecular adaptations. Adolescent male rats were subjected to a modified stress-enhanced fear learning (SEFL)-like paradigm followed by extinction training. Rats exposed to high-intensity fear conditioning (STRESSED groups) displayed persistent freezing and increased anxiety-like behaviour compared with non-shocked controls (NON-STRESSED groups). Repeated CE-123 administration during extinction significantly reduced freezing in stressed rats without affecting non-stressed animals. Quantitative proteomic analyses of the basolateral amygdala (BLA) and hippocampus (HPC) revealed marked region-specific effects. Stress-related fear enhancement induced extensive proteomic remodelling in the BLA, involving proteins associated with glutamatergic signalling, synaptic plasticity, and axonal organization, whereas the hippocampal proteome was largely unaffected. CE-123 also produced BLA-specific molecular effects, reducing the abundance of proteins associated with mitochondrial ATP synthesis in non-stressed animals and with ribosomal, mitochondrial, and RNA-processing pathways in stressed rats. These findings identify the BLA as a key substrate of fear-related molecular adaptations and demonstrate that selective DAT inhibition modulates amygdala proteomic architecture during fear extinction. Overall, the results support further investigation of DAT modulation as a potential strategy for facilitating fear extinction in stress-related disorders.
