Nausea and Gastric Myoelectrical Activity Are Influenced by Hormonal Contraception in Chronic Gastroduodenal Disorders.
Article in Clinical and translational gastroenterology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
introductionChronic gastroduodenal disorders are more prevalent among young women, many of whom are hormonal contraception users. We aimed to evaluate the effects of hormonal contraception on symptom severity and gastric myoelectrical activity in people with chronic gastroduodenal disorders.
methodsThis analysis was conducted on a large international cohort of patients who met Rome IV criteria for chronic nausea and vomiting syndrome or functional dyspepsia and had undergone body surface gastric mapping using Gastric Alimetry. Symptoms were continuously reported on 0-10 Likert scales using a validated symptom logging app.
resultsOne hundred twenty-seven people were included: 43 women using hormonal contraception, 30 not using hormonal contraception, 30 postmenopausal women, and 24 men. Hormonal contraception users had higher nausea than nonusers (3.80 [interquartile range 2.00-5.42] vs 2.25 [0.20-4.43]; P < 0.05), particularly when using combined oral contraceptives with hormone-free intervals compared with continuous use (5.20 [4.30-6.00] vs 2.40 [1.70-3.80], P = 0.02). Premenopausal women were more symptomatic than postmenopausal women and men ( P < 0.001). Principal Gastric Frequency was higher in hormonal contraception users (median 3.1 cpm vs 3.00 cpm, P < 0.001) and highest with progestogen-only formulations ( P < 0.02). DISCUSSION: Women with gastroduodenal disorders on hormonal contraception experience increased nausea in comparison with nonusers, with substantial variation dependent on contraceptive type. Hormonal contraception users also demonstrated modified gastric electrophysiology. These results imply that nonhormonal contraceptive alternatives should be trialled as a means to reduce symptoms in gastroduodenal disorders.
