Correlation between ultrasonographic measurements of the ileum and serum cobalamin concentrations in healthy cats and cats with chronic gastrointestinal signs: A pilot study.

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
Assessing intestinal health in cats with chronic gastrointestinal signs remains challenging. Serum cobalamin concentration is commonly used as a marker of ileal dysfunction, whereas ultrasonography enables morphological evaluation of the gastrointestinal tract. This study investigated the correlation between ultrasonographic ileal wall thickness and serum cobalamin concentrations in healthy cats and cats with chronic gastrointestinal signs. Twelve cats were divided into a symptomatic group (G1, n = 6) and a healthy control group (G2, n = 6) and underwent laboratory testing and abdominal ultrasonography. Mean ileal thickness was slightly greater in G1 (0.22 ± 0.03 cm) than in G2 (0.21 ± 0.02 cm), although the difference was not statistically significant (p = 0.48). Serum cobalamin concentrations also did not differ significantly between groups (p = 0.81). Correlation analysis demonstrated a weak, nonsignificant positive correlation in G1 and a moderate, nonsignificant correlation in G2. These findings suggest that ileal thickness alone is not a reliable predictor of serum cobalamin concentration and highlight the need for multifactorial diagnostic approaches and studies with larger sample sizes.
