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
objectiveTo evaluate the agreement between the overweight and obesity classifications of the World Health Organization (WHO), the International Obesity Task Force (IOTF), and the Brazilian Reference (BR) proposed by Conde and Monteiro in adolescents, and to verify the association of these classifications with cardiometabolic risk (CMR).
methodsA cross-sectional study was conducted with 823 adolescents (aged 10-19 years) from municipal schools in Fortaleza, Ceará. Nutritional status was classified according to three body mass index references. CMR was defined by the simultaneous presence of insulin resistance, identified by the waist-to-height ratio, and dyslipidemia, assessed by biochemical tests (total cholesterol, HDL-c, LDL-c, and triglycerides). Agreement between classifications was assessed using the Kappa (κ) statistic, and the association with CMR was analyzed using Poisson regression.
resultsAll classifications showed excellent agreement, with weighted κ values ranging from 0.85 to 0.95. The highest agreement was between WHO and IOTF references (κ=0.95; 95%CI 0.93-0.97), while the lowest was between WHO and BR (κ=0.85; 95%CI 0.82-0.88). Despite the lower agreement, the diagnosis of obesity according to the BR reference demonstrated strong clinical relevance, being associated with an 8.51-fold higher prevalence of CMR in adolescents (95%CI 6.38-11.35).
conclusionsBR showed a stronger association with CMR. The inclusion of this classification may optimize the early detection of CMR in Brazilian health services, helping to prevent cardiometabolic disorders in this population.
