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
The objective of this study is to elucidate the therapeutic mechanisms underlying silver needle thermal therapy (SNT) in alleviating skeletal muscle mitochondrial damage in a rat model of myofascial pain syndrome (MPS), with particular emphasis on its regulatory role concerning TRPV1/CaMKII. The MPS rat model was established through blunt impact and eccentric movement. Interventions included SNT and local intramuscular injections of anti-TRPV1 miRNA. Behavioral assessments were conducted to measure the mechanical and thermal pain thresholds of the rats. Histopathological staining was performed to evaluate muscle structure, while mitochondrial damage was assessed using transmission electron microscopy. Western blotting analysis was employed to quantify expression levels of TRPV1, CaMKII, and CytC. Additionally, immunofluorescence techniques were applied to analyze both the expression levels of TRPV1 and its co-localization with CaMKII. Following administration of SNT and anti-TRPV1 miRNA injections, a downregulation in the expression levels of TRPV1, CaMKII, and CytC within the muscle tissue of MPS rats was observed; concurrently, mitochondrial damage exhibited improvement. The implementation of SNT and the inhibition of TRPV1 lead to a reduction in CaMKII, thereby alleviating mitochondrial damage, indicating that TRPV1 is a potential target for silver needle thermal therapy of MPS.
