Impact of a 24 h feed withdrawal on active nutrient transport, intestinal morphology, and gene expression in the equine small and large intestine.

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
Horses are often subjected to short-term feed withdrawal (FW) pre- or post-surgery to reduce anesthetic complications. However, removing nutrients from the intestinal lumen may negatively impact intestinal health. Thirteen horses were used to determine the effects of a 24 h FW on gut barrier function, active nutrient transport, transporter gene expression, and intestinal morphology. Following 0 or 24 h FW (0FW or 24FW, respectively), horses were euthanized via overdose of sodium pentobarbital and sodium phenytoin, and segments of proximal jejunum (PJ), mid jejunum (MJ), ileum (Il), and right ventral colon (RVC) were harvested for histology (PJ and Il), gene expression, and active nutrient transport analysis. Active transport measurements were determined using modified Ussing chambers following the addition of glucose, phosphorus, glutamine, and Gly-Sar. Carbachol-induced chloride (Cl) ion secretion was measured to examine the diarrhetic response. Messenger RNA expression of the intestinal Na-dependent glucose cotransporter (SGLT1), fructose transporter (GLUT5), di- and tri-peptide transporter (PepT1), and neutral AA/glutamine transporter (ASCT2) were determined using RT-PCR. The GLM procedure of SAS was used to determine the effects of FW and responses among various intestinal sections. The horse served as the experimental unit. Villus heights (
