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
BACKGROUND AND
aimInsulin resistance and other metabolic risk factors are associated with increased cardiovascular diseases in animals fed with high fat diets (HFD). L-arginine is a semi-essential amino acid produced both endogenously and taken in the diet as supplements. It has been documented to possess antioxidant and anti-inflammatory properties and has been considered a plausible candidate for the management of metabolic disorders. Therefore, this study is aimed to determine the effects of L-arginine on lipid dysregulation and insulin resistance in high fat-fed male Wistar rats. METHODS AND
resultsTwenty-four (24) male Wistar rats randomly selected into 4 groups, mean weight 110 ± 5 and, (n = 6) were fed rat chow + distilled water (vehicle); CTR, rat chow + L-arginine (150 mg/kg), HFD + vehicle, HFD + L-Arginine (150 mg/kg) for 6 weeks. The animals were anesthetized with 50 mg/kg pentobarbital sodium intraperitoneally, blood sample was taken via cardiac puncture and thereafter collected into a heparinized tube. Data were expressed as means ± SEM. HFD increased body weight gain, serum Insulin, Homeostasis model assessment of insulin resistance (HOMA-IR), area under the curve (AUC), leptin, Lipoprotein(a) or Lp(a), triglyceride-glucose index (TYG), triglycerides (TG), free fatty acids (FFAs), total cholesterol (TC), low density lipoprotein (LDL-C), TC/HDL-C, Log TG/HDL-C, TC-HDL-C)/HDL-C but decreased phospoinositide-3-kinase (PIK3) when compared with control. L-arginine, resulted in significant reduction in weight gain, fasting blood sugar (FBS), insulin, AUC, HOMA-IR, leptin, while increasing PIK3, Lp(a), TG, TC and FFA when compared with HFD.
conclusionThe amelioration of lipid and glucose accumulation by L-arginine supplementation in high fat diet-fed male Wistar rats is accompanied by reduced leptin levels and PIK3 augmentation.
