Very-Low-Absorbable Geraniol for the Treatment of Irritable Bowel Syndrome: A "Real-World" Open-Label Study on 1585 Patients.

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
objectiveThe objective of this study was to evaluate the efficacy of a very-low-absorbable geraniol formulation, administered as a food supplement, in patients with irritable bowel syndrome (IBS) in a real-world setting in Italy.
methodsThis open-label study was conducted in Italy on patients diagnosed with IBS and treated for 4 weeks with 240 mg/day of Palmarosa essential oil, absorbed on 960 mg of ginger root powder to obtain a very-low-absorbable geraniol formulation. Baseline characteristics, including demographic and symptoms were recorded using the IBS Severity Scoring System (IBS-SSS). After 28 ± 7 days, the patients were asked to complete the IBS-SSS questionnaire again. The primary objective was to confirm the effects of a very-low-absorbable geraniol formulation on self-reported symptoms of IBS and the quality of life of affected individuals. The secondary objective was to confirm the effect of the treatment on the different IBS subtypes.
resultsA total of 1585 patients were included in the study, with a mean age of 44.8 years and 56.4% women. Following the 4-week supplementation period, significant decreases were observed in the patients' IBS-SSS (-67.9%) and all the primary IBS symptoms, such as abdominal distention (-82.3%), unsatisfaction with bowel habits (-46.2%), and interference with quality of life (QoL) (-64.9%) (all
conclusionsTreatment with very-low-adsorbable geraniol food supplement was associated with improvements in symptoms and bowel habits in all IBS subtypes in a real-world setting in Italy. These findings support the use of geraniol as an effective option for patients with IBS regardless of the disease subtype.
