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 relationship between dietary patterns and inflammatory markers in Brazilian adolescents with obesity.
methodsA cross-sectional analysis was conducted among 70 post-pubertal adolescents aged 15-19 years of both sexes who were classified as obese according to the World Health Organization criteria. Blood samples were collected to determine leptin and adiponectin levels using enzyme-linked immunosorbent assay kits, and the leptin/adiponectin ratio was calculated. Anthropometric measurements and body composition were assessed. Food intake was evaluated using a 24-hour dietary recall and categorized according to the NOVA classification into: fresh or minimally processed foods, processed culinary ingredients, processed foods, and ultra-processed foods. Participants were grouped according to sugar-sweetened beverage intake into intakers (n=41) and non-intakers (n=29).
resultsAdolescents who consumed sugar-sweetened beverages had higher fat-free mass, body weight, resting metabolic rate, and pro-inflammatory leptin/adiponectin ratio. They also showed greater intake of total grams, energy, proteins, lipids, cholesterol, carbohydrates, fiber, and saturated and polyunsaturated fats from ultra-processed foods. Additional analyses revealed that ultra-processed food intake was associated with increased body weight and higher waist and neck circumferences, which are relevant predictors of pro-inflammatory status.
conclusionThe findings suggest that sugar-sweetened beverage consumption and high ultra-processed food intake are associated with unfavorable anthropometric indicators and increased pro-inflammatory biomarkers, reflected by higher leptin/adiponectin ratios in adolescents with obesity.
