Associations of dietary habits and meal regularity with gastrointestinal symptoms, depression, and quality of life in patients with inflammatory bowel disease: a cross-sectional study.

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
backgroundInflammatory Bowel Disease (IBD) is a chronic and recurrent gastrointestinal disorder that adversely affects patients' quality of life. The influence of daily dietary behaviors and meal regularity on gastrointestinal symptoms and quality of life remains under-investigated. The study aimed to evaluate dietary intake, dietary habits, and meal patterns of the IBD patients and based on this data, to determine their gastrointestinal symptoms, quality of life, and depression status.
methodsThis cross-sectional study was conducted at Istanbul University Cerrahpaşa Medical Faculty Hospital and included adults aged 18-75 years with a confirmed diagnosis of IBD attending routine outpatient follow-up visits. Data were collected using a sociodemographic and clinical data form, a 24-Hour Dietary Recall, IBD Quality of Life Questionnaire (IBD-QoL), Beck Depression Inventory II (BDI-II), Gastrointestinal Symptom Rating Scale (GSRS).
resultsA total of 50 patients with IBD were included (30 Crohn's disease and 20 Ulcerative colitis). The mean age was 39.5 ± 13.49 years and the mean BMI was 24.82 ± 5.39 kg/m². Most patients (82%) reported consuming foods that worsened their symptoms, primarily legumes (21%), milk (14.3%), and raw vegetables (10.9%). Conversely, 50% identified foods that alleviated symptoms, mainly yogurt (18.2%) and cooked vegetables (18.2%), cooked meat (7.6%). Dietary analysis revealed intake below recommended levels for fiber, vitamins B1, B2, B6, C, folate, potassium, calcium, magnesium, and iron. Meal skipping was reported by 20% of patients with Ulcerative colitis and 40% with Crohn's disease. Patients who skipped meals had higher gastrointestinal symptom scores than those with regular meal patterns. Additionally, higher depression scores were associated with lower quality of life and more severe gastrointestinal symptoms.
conclusionThe study found that dietary intake and meal patterns in individuals with IBD are associated with their quality of life and gastrointestinal symptoms. A balanced and regular diet may be associated with reduced gastrointestinal symptoms and improved quality of life in IBD patients.
