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/Aims: Cyclic vomiting syndrome (CVS) and cannabinoid hyperemesis syndrome (CHS) are emerging gastroduodenal disorders with a growing prevalence. However, little is known about their prevalence and clinical characteristics in Latin American populations, particularly in Mexico. This study aims to explore the clinical presentation of CVS and CHS in Mexico. Methods: A cross-sectional study was conducted in 5 medical centers across Mexico, involving patients diagnosed with CVS or CHS based on the Rome IV criteria. Data collected included sociodemographic variables, substance use, comorbidities, and clinical characteristics, with a specific focus on the relationship between substance use, particularly cannabis, and symptomatology. Results: The study included 46 patients, with 30 diagnosed with CVS and 16 with CHS. CVS patients were younger (median age 23 years) compared to CHS patients (median age 27 years; Conclusions: This study presents the first detailed analysis of CVS and CHS in the Mexican population, revealing some demographic and clinical differences from global data. These findings highlight the importance of developing region-specific guidelines for diagnosing and managing these conditions, especially given Mexico's changing cannabis policies.
