CTRP3 alleviates neuropathic pain by improving mitochondrial biogenesis and mitochondrial unfolded protein response via spinal SIRT1 in rats.

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
Neuropathic pain arises from an intricate network of interconnected pathophysiological mechanisms, yet the arsenal of effective therapeutic strategies remains frustratingly limited. Accumulating evidence has linked mitochondrial dysfunction to the progression of neuropathic pain. C1q‑tumor necrosis factor‑related protein‑3 (CTRP3), a newly identified adipokine with diverse cytoprotective capacities, has not been previously explored for its role in nociceptive processing. To explore the role of CTRP3 in pain hypersensitivity, pain‑related behavioral assessments were conducted using von Frey filaments and acetone drop method in male rats subjected to spared nerve injury (SNI). To unravel the underlying mechanisms, spinal cord tissues were subjected to western blotting, reverse transcription‑quantitative PCR, immunofluorescence staining, dihydroethidium staining, small interfering RNA (siRNA) technologies and biochemical assays for quantifying oxidative markers. The findings showed that SNI markedly reduced endogenous CTRP3 expression in spinal neurons. Intrathecal administration of recombinant CTRP3 (rCTRP3) alleviated mechanical allodynia and cold hyperalgesia in SNI‑induced rats. Additionally, rCTRP3 treatment enhanced PGC‑1α‑mediated mitochondrial biogenesis, ATF5‑triggered mitochondrial unfolded protein response (UPR
