PPARα agonist relieves spinal cord injury in rats by activating Nrf2/HO-1 via the Raf-1/MEK/ERK pathway.
Article in Aging, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 papers.
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
objectiveTo observe the inhibitory effects of the peroxisome proliferator-activated receptor alpha (PPARα) agonist palmitoylethanolamide (PEA) on inflammatory responses and oxidative stress injury in rats with spinal cord injury (SCI).
methodsThe SCI rat model was established using modified Allen's method and the changes in rats' joint motion were observed by Basso, Beattie and Bresnahan locomotor rating scale (BBB scale) at 1, 3 and 7 days after modeling, HE Staining and Nissl Staining has been carried out to evaluate the pathological lesion of spinal cords in rats. Besides, Immunohistochemical (IHC) was performed to detect the reactive oxygen species (ROS), expression levels of acrylamide (ACR) and manganese superoxide dismutase (MnSOD) in rat spinal cords, and Western Blotting was applied to measure protein expression levels of nuclear factor-kappa B (NF-κB), B cell lymphoma-2 (Bcl-2), BCL-2 associated X (BAX), phosphoinositide 3-kinase (PI3K), protein kinase B (Akt), phosphorylated (p)-Akt, HO-1, Nrf2, trithorax-1 (TRX-1), Raf-1, MEK, ERK, p-MEK and p-ERK.
resultsThe PPARα agonist PEA could alleviate SCI in rats, inhibit inflammatory responses, mitigate oxidative stress injury, reduce the apoptotic rate and promote SCI rats motor function recovery. In addition, the PPARα agonist PEA was able to activate the phosphorylation of MEK and ERK, stimulate Nrf-2 translocation into the nucleus and up-regulate the expressions of HO-1 and TRX-1.
conclusionPPARα agonist PEA can relieve SCI in rats by inhibiting inflammatory responses and oxidative stress, which may involve a mechanism associated with the activation of Nrf2/HO-1 via the Raf-1/MEK/ERK pathway.
