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
backgroundObesity and hypertension are major risk factors for cardiovascular target organ damage in childhood, including increased left ventricular mass index (LVMI) and left ventricular hypertrophy (LVH). Blood pressure variability (BPV) has been suggested as a potential contributor to cardiovascular damage; however, its role in pediatric obesity remains unclear. This study was aimed at evaluating short-term BPV and pulse wave analysis (PWA) parameters in children and adolescents with obesity and their associations with LVMI and LVH.
methodsThis retrospective cross-sectional study included 42 children and adolescents with obesity evaluated between October 2023 and August 2025, and 42 age- and sex-matched healthy children and adolescents (8-18 years). All participants underwent 24-h ambulatory blood pressure monitoring with simultaneous PWA and echocardiographic assessment of LVMI. Short-term BPV was assessed using standard deviation (SD), coefficient of variation (CV), and average real variability (ARV). LVH was defined as LVMI above the 95th percentile for age and height. Correlation analyses and multivariable logistic regression analysis were performed.
resultsParticipants with obesity had higher ambulatory blood pressure levels, BPV indices, pulse wave velocity and central blood pressure values than healthy controls (p < 0.05). LVH prevalence was higher in the obese group (40% vs. 9%; OR = 6.29, 95% CI: 1.90-20.9). Short-term BPV parameters were not independently associated with LVH and showed no significant correlations with LVMI or the LVMI ratio.
conclusionsDespite increased BPV and arterial stiffness in children and adolescents with obesity, short-term BPV was not independently associated with LVMI or LVH. Further prospective studies are warranted to clarify the clinical relevance of BPV in pediatric obesity.
