Effect of phenylbutazone administration on the enteroinsular axis in horses with insulin dysregulation.
Article in Journal of veterinary internal medicine. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundPhenylbutazone is prescribed for laminitis-associated pain and decreases glucose and insulin responses to an oral glucose test (OGT) in horses with insulin dysregulation (ID). HYPOTHESIS/
objectivesInvestigate the effect of phenylbutazone administration on the enteroinsular axis in horses. ANIMALS: Sixteen horses, including 7 with ID.
methodsRandomized cross-over study design, with horses assigned to treatment with phenylbutazone (4.4 mg/kg IV q24h) or placebo (5 mL 0.9% saline). On Day 9 of treatment, an OGT was conducted, followed by a 10-day washout period, administration of the alternative treatment, and repetition of the OGT. Glucose-dependent insulinotropic polypeptide (GIP), and active glucagon-like peptide 1 and 2 (aGLP-1 and GLP-2) concentrations were determined by ELISA. The effects of ID status and treatment on peptide concentrations were assessed using t tests and analyses of variance.
resultsHorses with ID had significantly higher maximum GIP concentrations (Cmax) than controls (median, 279.1; interquartile range [IQR], 117.5-319.4 pg/mL vs median, 90.12; IQR, 74.62-116.5 pg/mL; P = .01), but no significant effect of ID was detected on aGLP-1 and GLP-2 concentrations. In horses with ID, phenylbutazone treatment significantly decreased GIP Cmax compared with placebo (168.1 ± 59.26 pg/mL vs 242.8 ± 121.8 pg/mL; P = .04), but no significant effect of phenylbutazone was detected on aGLP-1 and GLP-2 concentrations. CONCLUSION AND CLINICAL IMPORTANCE: Glucose-dependent insulinotropic polypeptide, aGLP-1 and GLP-2 do not mediate the decrease in glucose and insulin concentrations observed after phenylbutazone administration. Only GIP was repeatedly associated with ID status, calling into question the role of the enteroinsular axis in ID.
