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
Impairment of neuronal plasticity is involved in a spectrum of neurological disorders such as epilepsy, yet its regulatory mechanisms remain incompletely understood. Here, it is reported that the basic helix-loop-helix transcription factor DEC2 serves as a pivotal regulator of both neuronal plasticity and epileptogenesis through its repression of sodium voltage-gated channel alpha subunit 2 (SCN2A). Knockdown of DEC2 in hippocampal neurons elevates intrinsic excitability and synaptic transmission, exacerbating seizure susceptibility and severity. Conversely, overexpression of DEC2 in hippocampus reduces intrinsic excitability and synaptic transmission, ultimately decreasing seizure susceptibility. Mechanistically, DEC2 functions as a transcriptional repressor of Scn2a by directly binding class B E-boxes (CACGTG) in its promoter. Additionally, DEC2 forms complexes with myoblast determination protein 1 (MYOD1) and occupies the CAGCTG E-boxes within the Scn2a promoter; however, this interaction does not affect Scn2a transcription in vivo. These findings also reveal that cannabidiol (CBD) can modulate the DEC2-SCN2A axis. Notably, CBD predominantly enhances DEC2's direct transcriptional repression of SCN2A. In summary, this study identifies DEC2 as a critical regulator of neuronal plasticity in epilepsy progression, suggesting a novel therapeutic pathway for epilepsy treatment.
