Longitudinal Analysis of Gastroesophageal Reflux Disease and Its Impact on Cardiovascular Function and Development of Hypertension in Pediatric Populations: A Multi-center Study.
Article in Cureus, 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
backgroundGastroesophageal reflux disease (GERD) is increasingly recognized as a condition with systemic effects extending beyond the gastrointestinal tract.
objectiveTo evaluate the long-term impact of GERD on cardiovascular function and the development of hypertension in pediatric populations through a multi-center, one-year longitudinal analysis.
methodsThis longitudinal study was conducted at The Children's Hospital, Lahore, and Allied Hospital, Faisalabad, from June 2024 to May 2025. A total of 285 children aged 5-16 years with confirmed GERD were enrolled from multiple tertiary care hospitals. Participants underwent baseline assessments including clinical evaluation, anthropometry, blood pressure measurement, echocardiography, heart rate variability (HRV) analysis, and inflammatory biomarkers (CRP, IL-6, TNF-α).
resultsOver the three-year period, 48 children (16.8%) developed hypertension, with the highest incidence in the severe GERD group (30.7%). Systolic blood pressure increased significantly from 106.8 ± 8.9 mmHg at baseline to 114.7 ± 10.1 mmHg at 36 months (p < 0.001). Children with moderate and severe GERD showed marked reductions in HRV and increased low frequency/high frequency (LF/HF) ratios, indicating sympathetic predominance. Inflammatory biomarkers rose progressively, with CRP correlating positively with systolic blood pressure (r = 0.38, p < 0.01). Echocardiography revealed significant increases in left ventricular mass index over time, particularly in severe GERD cases. Multivariate analysis identified severe GERD (β = 0.31, p < 0.001), elevated CRP (β = 0.27, p = 0.002), and higher BMI (β = 0.22, p = 0.008) as independent predictors of hypertension.
conclusionGERD in pediatric populations is associated with progressive cardiovascular alterations, including rising blood pressure, autonomic dysregulation, systemic inflammation, and early cardiac remodeling.
