Effects of Earthquake Fear and Post-Traumatic Stress Disorder on Patients with Irritable Bowel Syndrome after a Major Earthquake in Türkiye: A Multicenter Study.
Article in The Turkish journal of gastroenterology : the official journal of Turkish Society of Gastroenterology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
BACKGROUND/
aimsOn February 6, 2023, 2 devastating earthquakes struck south-eastern Türkiye, causing over 100 000 injuries and more than 50 000 deaths. This study aimed to investigate the impact of post-traumatic stress disorder (PTSD) and fear of earthquake on the severity of irritable bowel syndrome (IBS) symptoms and IBS-related quality of life (IBS-QoL). MATERIALS AND
methodsParticipants diagnosed with IBS were categorized into 2 groups: those residing in earthquake zones and those in non-earthquake zones. Data regarding demographic characteristics, IBS Symptom Severity Scale (IBS-SSS), IBS-QoL, Post-traumatic Stress Disorder Checklist for Diagnostic and Statistical Manual of Mental Disorders-5th edition (PCL-5), and Fear of Earthquake Scale (FES) were collected through validated questionnaires. Multivariate analyses, multiple linear regression, and elastic net (EL) models were performed to identify predictors of IBS-SSS and IBS-QoL scores.
resultsA total of 225 IBS patients were included, with 117 (52%) from earthquake zones and 108 (48%) from non-earthquake zones. Mean IBS-SSS, IBS-QoL, FES, and PCL-5 scores were significantly higher in the earthquake group compared to the non-earthquake group (249 vs. 141; 44.1 vs. 22.8; 20 vs. 9; 47 vs. 28, respectively; P < .001 for all). The PCL-5 and FES scores were independent predictors of IBS-SSS (OR = 1.057, P < .001 and OR = 1.082, P = .019). In regression and EL models, PCL-5 (P < .001) was the strongest predictor (100%) and FES (P = .006) the second (38%) for IBS-QoL.
conclusionThe PTSD and earthquake-related fear significantly impact IBS symptom severity and QoL. A holistic treatment approach addressing psychosomatic and mental health factors may improve outcomes in IBS patients. Cite this article as: Cankurtaran RE, Karpuzcu HC, Ataman E, et al.
