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
Gastroesophageal reflux disease (GERD) and its manifestation as reflux esophagitis (RE) involves mucosal inflammation and autonomic dysfunction. Vitamin D3 deficiency is increasingly implicated in gastrointestinal inflammation and immune imbalance. This study investigated the therapeutic and prophylactic effects of 1,25-dihydroxyvitamin D3 on esophageal inflammation and autonomic nervous system disruption in a non-surgical rat model of RE. RE was induced via intermittent fasting and refeeding. Rats received either no treatment, prophylactic vitamin D3 (1250 IU/day pre- and post-induction), or therapeutic vitamin D3 (post-induction only). We assessed esophageal histopathology, immunohistochemical expression of tumor necrosis factor α (TNF-α) and transforming growth factor β (TGF-β), serum interleukin 6 (IL-6) levels via ELISA, and heart rate variability (HRV) indices. RE rats exhibited characteristic mucosal damage, elevated IL-6 and TNF-α expression, and impaired HRV (reduced standard deviation of normal to normal intervals (SDNN), High frequency (HF); increased low frequency/high frequency ratio (LF/HF)). Vitamin D3 supplementation significantly reversed these alterations. Prophylactic administration showed superior efficacy in preserving mucosal integrity and autonomic function compared to therapeutic intervention. Notably, TNF-α expression was abolished and IL-6 was significantly reduced. 1,25-dihydroxyvitamin D3 exerts protective and therapeutic effects in RE through suppression of inflammatory cytokines and restoration of autonomic balance. These findings support its potential as a neuroimmune modulator in esophageal inflammatory diseases. Heart rate variability (HRV) was assessed as an autonomic marker, and correlations with cytokine levels were explored. Scale bars and schematic workflow diagrams were included for clarity. A Limitations section was added to acknowledge constraints such as absence of a DMSO control.
