Antibiotic-associated diarrhea in children hospitalized with pneumonia and preventive effect of bifidobacterium animalis ssp. lactis B94 use: a single-center, retrospective preliminary observational report.

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
introductionAntibiotic-associated diarrhea (AAD) is known to be a common problem in children receiving antibiotic treatment. However, there is insufficient data in children hospitalized with a diagnosis of pneumonia. The aim of our study was to evaluate the incidence of AAD in children hospitalized with a diagnosis of pneumonia without known comorbidities and to investigate the protective effect of Bifidobacterium animalis ssp. lactis B94 against diarrhea. POPULATION AND
methodsWe conducted a retrospective preliminary observational study in children diagnosed with pneumonia who were admitted to the Department of General Pediatrics at a Tertiary Hospital in the Mediterranean Region of Turkey between January 2021 and December 2023. Children diagnosed with pneumonia who met the study criteria were included in the study. AAD was defined as ≥ 3 loose or watery stools per day for a minimum of 48 h during antibiotic treatment. For patients with AAD, clinical data, antibiotic use, diarrhea incidence, and probiotic use were recorded.
resultsA total of 202 patients were enrolled. Of these, 116 (57.4%) were female, with a median age of 33.6 months. AAD developed in 14 patients (6.9%). AAD developed more frequently in children younger than 24 months (p = 0.004). Age and gender distribution were similar between the probiotic and control groups (p > 0.05). AAD developed significantly less in the probiotic group (2.9% vs. 11.0%, p = 0.022). After multivariate adjustment, probiotic use remained protective (adjusted OR: 2.435, 95% CI: [(1.464)-(2.717), p = 0.031]). Additionally, children given probiotics required less IV hydration (1.9% vs. 8.0%, p = 0.041).
conclusionThis preliminary observational study suggests the incidence of AAD is low among children hospitalized with pneumonia without comorbid diseases. Prophylactic use of Bifidobacterium animalis ssp. lactis B94 may reduce the risk of diarrhea, though larger prospective studies are needed for confirmation.
