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

Trigeminal neuralgia is a chronic pain disorder due to neuronal damage. The present study was designed to investigate the effect of 7,8-dimethoxy coumarin (DMC) in a rat model of trigeminal neuralgia. The neuropathic pain was induced by the single endoneural injection of tumor necrosis factor-alpha (TNF-α; 0.1 μL: stock 10 pg/mL) in the rat trigeminal nerve. The DMC (100 and 200 mg/kg) and carbamazepine (100 mg/kg) were administered orally for 10 consecutive days from the 5th day of TNF-α injection. The battery of behavioral tests, i.e., acetone drop and Von Frey filament test, was performed to assess the degree of thermal and mechanical allodynia on 0, 1st, 7th, and 14th days. In addition, the biochemical tests, i.e., total protein, thiobarbituric acid reactive substances (TBARS), reduced glutathione (GSH), and TNF-α, were also performed in trigeminal nerve tissue. Furthermore, TNF-α-induced neuronal histopathological changes were also evaluated by the eosin and hematoxylin staining method. The administration of DMC was shown to demonstrate the significant (
