Anti-CdtB and anti-vinculin antibodies to diagnose irritable bowel syndrome in inflammatory bowel disease patients.
Article in BMC gastroenterology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
backgroundDespite adequate treatment, a subgroup of patients with inflammatory bowel disease (IBD), including Crohn`s disease and ulcerative colitis, have persistent gastrointestinal symptoms that are not always related to mucosal damage. Recently, two autoantibodies, anti-CdtB and anti-vinculin, were validated as post-infectious IBS (PI-IBS) markers, however there is limited evidence of its diagnostic role in IBD population.
methodsPatients with more than 3 bowel movements/day and indication of colonoscopy were enrolled. Samples were collected at the time of colonoscopy for assessment of serum levels of anti-CdtB and anti-vinculin antibodies.
resultsA total of 160 subjects were included in 4 groups: active IBD (n = 44); quiescent IBD and chronic diarrhea IBD-IBS (n = 25); predominant-diarrhea IBS (n = 45) and controls (n = 46). The mean value of the optical density for anti-CdtB was 1.2 ± 0.65 in group 1, 1.27 ± 0.64 in group 2, 1.49 ± 0.47 in the group 3 and 1.6 ± 0.68 in group 4, p = 0.012. For anti-vinculin, optical densities were: 1.34 ± 0.78 in group 1, 1.46 ± 0.92 in group 2, 1.31 ± 0.79 in group 3 and 1.41 ± 0.86 for controls (p = 0.875). Using a cut-off of 1.56 for anti-CdtB, the positivity between groups was n = 10 (22.7%) in group 1, n = 9 (34.6%) in group 2, 19 (43.2%) in group 3, 21 (45.7%) in group 4 (p = 0.106). The positivity of anti-vinculin using a cut-off of 1.6 was n = 18 (40.9%) in group 1, n = 11 (42.3%), n = 15 (34.1%), n = 22 (47.8%) (p = 0.622).
conclusionsOur findings show that anti-CdtB and anti-vinculin could not identify IBD-IBS patients or discriminate IBS-D from healthy controls.
