Clinical and microbiological profile of patients with diarrhea evaluated using the gastrointestinal panel in a high-complexity center.
Observational study in BMC gastroenterology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
introductionGastrointestinal infections represent a worldwide public health problem. In Colombia, the incidence reaches 21.4 cases per 1,000 inhabitants. Given the limitations of traditional diagnostic methods in terms of sensitivity and specificity, the gastrointestinal panel (GIP) has emerged as a promising tool, allowing rapid detection of 22 pathogens. This study aimed to describe the clinical and microbiological characteristics of immunosuppressed and immunocompetent adult patients with diarrhea and the influence of the gastrointestinal panel in their treatment in a high-complexity hospital in Colombia. MATERIALS AND
methodsA cross-sectional observational study was carried out including 350 adult patients treated at the Fundación Valle del Lili hospital between 2021 and 2022. Demographic and clinical variables, GIP findings and treatment were analyzed by univariate and bivariate analysis. We compare immunocompromised and immunocompetent adult patients using Chi-square tests, Fisher's F test for qualitative variables, Student's t-test, and the Mann-Whitney U test for quantitative variables. A significance level of 5% was applied to demonstrate the significance of the variables in all the tests used.
resultsThe results showed that 52% were men, with an average age of 52 years. 72.0% presented acute diarrhea, being inflammatory in 60.1%. 39.1% of the patients were immunosuppressed, mainly transplant recipients (31.3%). 53% of the GIPs were positive, with up to 5 pathogens per sample. Bacteria were detected in 80%, viruses in 14.4%, and parasites in 5.5%. The most frequent bacteria were enteropathogenic E. coli (43.0%), enteroaggregative E. coli (18.6%), and C. difficile (17.4%). Norovirus was the predominant virus (67.7%) and Cryptosporidium the most common parasite (41.7%). A higher frequency of Vibrio spp. was observed in non-immunosuppressed patients (p = 0.004) and of enterotoxigenic E. coli in immunosuppressed patients. 41.0% of patients received antibiotic/antiviral therapy, 83% empirically. GIP influenced the treatment of 56.7% of patients, with a 90.0% recovery rate.
conclusionThis study confirms that GIP is a valuable diagnostic tool in the management of adult patients with diarrheal disease, particularly in immunocompromised patients. In our setting it is still a costly and difficult to access test, which makes it necessary to standardize the indications for its application. Future studies could evaluate its cost-effectiveness in our context.
