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

backgroundCognitive impairment is a common complication in patients with chronic neuropathic pain, without effective therapy. Recent works have indicated that curcumin (Cur) possesses antinociceptive and neuroprotective potentials, suggesting its possible effectiveness for the treatment of this complication.

objectiveThe aim of this study was to explore the effects of Cur on pain behaviors and cognitive impairment in rats with cobra venom-induced trigeminal neuralgia (TN).

designThis is a randomized, controlled experiment.

settingThis study was conducted at the Experimental Animal Center, Beijing Friendship Hospital, Capital Medical University. SUBJECTS: A total of 40 adult male Sprague Dawley rats were used in this study.

methodsA cobra venom solution was injected into the sheath of infraorbital nerve. Cur was administered intragastrically at 45 mg/kg twice daily for 28 successive days from postoperative day 15. Mechanical allodynia was evaluated using von Frey filaments. Free behaviors were observed using video recording. Cognitive capacity was tested using the Morris water maze. Both morphology and ultrastructure of the CA1 hippocampal region were visualized using hematoxylin and eosin (HE) staining and transmission electron microscopy, respectively.

resultsCur treatment reduced mechanical allodynia and face-grooming activities but increased exploratory activities and improved spatial learning and memory deficits. Microscopic examination revealed nucleus pyknosis, swollen organelles, and decreased synapse density in the CA1 hippocampal region after cobra venom injection. However, chronic Cur treatment reversed damage to hippocampal neurons and synapses.

conclusionCur can alleviate pain, improve spatial learning and memory deficits, and restore the damage to hippocampal neurons and synapses in cobra venom-induced TN rats. Cur may be useful as an adjuvant to treat chronic neuropathic pain-induced cognitive deficits.
