Electroacupuncture with different current intensities can improve gastrointestinal motility in diabetic gastroparesis
Article in World journal of diabetes, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundDiabetic gastroparesis (DGP) disrupts gastric motility. Electroacupuncture (EA) at Zusanli (ST36) may alleviate DGP symptoms
aimTo investigate how EA current intensities at ST36 regulate neural pathways and improve gastric motility in DGP models.
methodsA DGP model was established using intraperitoneal injection of streptozotocin. Gastrointestinal motility was measured in rats after 2 weeks of continuous EA at ST36. Current intensity was selected as 0.5 mA, 1 mA, and 3 mA. Gastric electrodynamics were detected by recording and analyzing the number of gastric discharges. The gastric emptying rate and propulsion rate of the small intestine were measured to assess dynamic gastrointestinal function. Hematoxylin-eosin staining was conducted to measure histopathological changes in the gastric sinus. Reverse transcription-polymerase chain reaction was conducted to determine mRNA levels of Rho guanine nucleotide-binding protein A and Rho-associated coiled-coil forming protein kinase. Western blotting was conducted to determine the expression levels of choline acetyltransferase, tyrosine hydroxylase, Rho guanine nucleotide-binding protein A, and Rho-associated coiled-coil forming protein kinase. Immunofluorescence staining in the stomach was conducted to detect the distribution of C-kit, an interstitial cell of Cajal marker. An enzyme-linked immunosorbent assay was conducted to detect serum levels of acetylcholine and norepinephrine.
resultsTreatment with EA improved gastric emptying and gastric smooth muscle disorders in rats with DGP, mitigated pathological damage, and restored the function of interstitial cells of Cajal. In addition, different current intensities of EA affected gastrointestinal function of rats with DGP. The 0.5 mA, 1 mA, and 3 mA EA groups all improved gastrointestinal function. 0.5 mA EA increased acetylcholine levels by increasing protein expression of choline acetyltransferase (
conclusionEA with ST36 improved gastric motility in rats with DGP. 0.5 mA EA activated the vagus nerve, while 3 mA EA regulated gastrointestinal motility by activating the sympathetic nerves.
