1 · What the graph read from it

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.

2 · The registry

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

Objective: Methods: The composition of LT was determined using HPLC (High-Performance Liquid Chromatography). The control group received only tap water via the oral route for 14 days. The indomethacin-only group was administered 100 mg/kg indomethacin in a single oral dose following 24-h fasting. The indomethacin + famotidine group received 40 mg/kg famotidine via the oral route 1 hour before gastric ulcer induction. The members of the indomethacin + LT group received oral LT for 14 consecutive days. A gastric ulcer was induced after 24-h of fasting, and the experimental groups were sacrificed at the end of the sixth hour. Malondialdehyde, glutathione, cyclooxygenase 1 and 2, vascular endothelial cell growth factor A, nuclear factor kappa B, cleaved Poly ADP-ribose polymerase, pan-Akt, and p-Akt levels were examined at the tissue level. Results: Oxidative stress and inflammation, increased by indomethacin, activated the apoptotic cascade. LT showed partial anti-oxidative changes but significantly suppressed PARP-1 expression. The limited bioavailability of catechins may have restricted protective efficacy. Conclusion: The research showed that LT may be a promising agent with partial antioxidant, anti-inflammatory, and anti-apoptotic properties.
