Correlation between intestinal ultrasound and fecal calprotectin with endoscopic severity scores for determining the activity in patients with Crohn's disease.
Observational study in Abdominal radiology (New York), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundCrohn's disease (CD) is a chronic inflammatory bowel disease characterized by relapsing and remitting inflammation of the gastrointestinal tract. Reliable and non-invasive methods to assess disease activity are crucial for guiding treatment and improving patient outcomes. This study investigates how intestinal ultrasound (IUS) parameters and fecal calprotectin (FC) levels correlate with endoscopic severity scores in Crohn's disease (CD). AIM AND
objectiveTo assess the effectiveness of IUS as a complementary tool to conventional methods in predicting disease severity in CD by correlating IUS parameters, specifically bowel wall thickness (BWT) and color Doppler flow (CDF), with FC levels and Simple Endoscopic Score for Crohn's Disease (SES-CD). MATERIALS AND
methodsA cross-sectional observational study was conducted on 45 patients with confirmed CD at the Department of Gastroenterology. Clinical data, FC levels, SES-CD scores, and IUS measurements were collected and analyzed. The correlation between BWT, FC, and SES-CD scores was assessed using Pearson correlation, and the sensitivity and specificity of combined IUS and FC parameters were calculated.
resultsThe study found significant correlations between higher CDF scores and increased FC levels in the ileum (P = 0.002) and ascending colon (P < 0.001). BWT showed a significant positive correlation with SES-CD in the descending colon (r = 0.440, P = 0.003) and rectosigmoid (r = 0.366, P = 0.014). The combination of BWT > 3 mm and FC > 250 µg/g demonstrated high sensitivity and specificity, particularly in the ileum (sensitivity 88.6%, specificity 78.9%) and descending colon (sensitivity 80.9%, specificity 87.7%).
conclusionCombining IUS parameters, particularly BWT and CDF, with FC levels provides a robust method for predicting disease severity in CD. This approach can enhance disease monitoring, reduce reliance on invasive procedures, and improve patient management in clinical practice.
