Prevalence of Preclinical and Clinical Obesity Among US Children and Adolescents Aged 5 to 18 Years: NHANES 2017-2023.

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
objectiveThis study aimed to estimate the prevalence of preclinical and clinical obesity among US youth using the Lancet Diabetes & Endocrinology Commission's framework.
methodsThis cross-sectional study examined NHANES 2017-2023 data from 5513 youth aged 5-18. Obesity classification included: (i) no obesity (BMI < 95th percentile and/or waist to height ratio (WHtR) < 0.5), (ii) preclinical obesity (BMI ≥ 95th percentile and WHtR ≥ 0.5 without clinical impairment or functional limitations), and (iii) clinical obesity (BMI ≥ 95th percentile and WHtR ≥ 0.5 with one or more clinical impairments or functional limitations).
resultsThe weighted prevalence was 8.3% for preclinical and 12.5% for clinical obesity; combined prevalence (20.8%) was similar to ~22% using BMI percentile alone. Clinical obesity was more common in older children and racial/ethnic minority groups but similar by sex. Impairments associated with clinical obesity included low HDL cholesterol (60.3%), asthma (24.8%), early menarche in girls (18.0%), elevated blood pressure (16.2%), prediabetes/diabetes (9.1%), and functional limitations related to walking (7.7%) and self-care (4.1%).
conclusionsApplying the Lancet Diabetes & Endocrinology Commission's new definition criteria revealed substantial physiological dysfunction in US youth. Applying preclinical and clinical obesity definitions is challenging, given the limitations of the routinely collected clinical and epidemiological data that make up NHANES and in standard clinical practice.
