Clinical and radiological features of gastric and small intestinal anisakiasis: comparison with gastric ulcers and crohn's disease.

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
purposeTo compare the clinical and radiological features of gastric and small intestinal anisakiasis with those of gastric ulcers and Crohn's disease. MATERIALS AND
methodsIn this retrospective cohort study, 205 cases of anisakiasis (148 gastric; 53 small intestinal) were identified between July 2003 and February 2022. The control groups included 130 and 31 patients with gastric ulcers and Crohn's disease, respectively. Clinical and imaging findings were compared between the groups using the chi-square test, Fisher's exact test, Mann-Whitney U test, and t-test.
resultsPatients with gastric anisakiasis were younger (median age, 40 [21-85] years; 87 men) than those with gastric ulcers (median age, 64.5 [29-90] years; 101 men). Abdominal pain was common in the gastric anisakiasis group, whereas bleeding symptoms were frequent in the gastric ulcer group. Patients with small intestinal anisakiasis were older (mean age, 51.2 [38.6-63.7] years; 44 men) than those with Crohn's disease (mean age, 35.9 [21.6-50.3] years; 22 men). Patients with gastric anisakiasis exhibited more edematous wall thickening, increased surrounding fat density, ascites, and thickening of other intestinal walls than those with gastric ulcers. Patients with small intestinal anisakiasis showed greater wall edema, perienteric fat stranding, proximal dilatation, clamp sign, and ascites than those with Crohn's disease. Interobserver agreement was moderate to excellent, except for esophageal findings.
conclusionAnisakiasis demonstrates clinical and radiological features distinct from those of gastric ulcers and Crohn's disease. Recognizing these differences may aid in the differential diagnosis of gastrointestinal disorders, particularly in regions with high levels of raw fish consumption. This retrospective study compared CT findings of gastric and small intestinal anisakiasis with gastric ulcers and Crohn's disease. Anisakiasis exhibited distinct features, including edematous wall thickening, increased surrounding fat density, and ascites. These findings can aid in differential diagnosis, particularly in regions where raw fish consumption is common.
