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
Shorea robusta (Dipterocarpaceae), a timber-producing tree, that thrives in India, Bangladesh, East Himalaya, Nepal, Tibet, and West Himalaya regions. Traditionally, different parts of this plant have been used for several pharmacological activities. The present study was aimed to validate the hepatoprotective mechanisms of Shorea robusta in in silico, in vitro and in vivo model. The methanolic extract of Shorea robusta (MESR) bark was analyzed using UHPLC-Q-TOF-MS, revealing 68 numbers of phytoconstituents. Based on Lipinski’s Rule of Five and ADMET analysis, 15 major phytoconstituents were selected for molecular docking studies against hepatoprotective targets such as TNF-α, TGF-β1, and PPAR-α. In vitro antioxidant study was evaluated using DPPH and ABTS assays. Hepatoprotective efficacy was assessed in an isoniazid (INH)-induced hepatotoxicity rat model through biochemical parameters, cytokine analysis, histopathology, and immunohistochemistry. Molecular docking analysis revealed that Lysidiside N (-11.0 kcal/mol), polydatin (-10. Kcal/mol), resveratrol 12-C-beta-glucopyranoside (-10. Kcal/mol), alpinetin (-9.2 Kcal/mol), and ellagic acid (-9.1 Kcal/mol) displayed the highest docking score toward TNF-α, TGF-β1, and PPAR-α. MESR exhibited high total phenolic (29.922 mg GAE/g D.W.) and flavonoid content (29.74 mg QE/g D.W.), with strong antioxidant properties (DPPH: IC50 = 39.12 µg/mL; ABTS: IC50 = 37.68 µg/mL). Oral administration of MESR (500 mg/kg) was significantly restored altered liver enzymes, protein, and lipid profiles, along with cytokine levels. Histopathological and immunohistological analyses revealed marked improvement in the liver architecture, indicating enhanced hepatoprotection in the treated group. Collectively, MESR at a dose of 500 mg/kg exhibited a pronounced hepatoprotective activity against INH-induced hepatotoxicity in experimental rats. Lysidiside N, Polydatin, resveratrol 12-C-β-glucopyranoside, alpinetin, and ellagic acid may be considered as the major phytoconstituents contributing to the hepatoprotective activity of S. robusta bark.
