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 temporal trend of dietary practices of adolescents monitored in Primary Health Care from 2015 to 2019.
methodsThis is a time series study with microdata on adolescent food consumption markers (n=674,280 records, mean age: 14.9 [standard deviation: 3.0] years, 65.0% girls) held on the Food and Nutrition Surveillance System. Annual prevalence of each marker was calculated, in addition to the following indicators: combined consumption of beans, fruit, vegetables and greens; and ultra-processed food. Prais-Winsten regression was used to calculate the annual increase rate, according to sex, age group (10-14 years, 15-19 years) and macro-regions. Increasing or decreasing trends were denoted by a positive or negative annual increase rate with p-value<0.05.
resultsThe prevalence rates of consumption of beans, fruit, vegetables and legumes in 2019 were 83.0%, 69.0% and 65.0%. The combined indicator of beans, fruit, vegetables and legumes was found in 48.0% of adolescents in 2019, with a rising trend in Brazil as a whole (annual increase rate: +4.0%, 95% confidence interval [95%CI 0.4; 6.6]), in the 15-19 age group and in the Southeast region. In 2019, markers of ultra-processed food consumption were frequent among adolescents (burgers and sausages: 45.0%, sugar-sweetened drinks: 65.0%, instant noodles/snacks: 46.0%, sweets: 55.0%). The prevalence of the ultra-processed food indicator in 2019 was 23.0%, with a rising trend nationally (annual increase rate: +7.0%, 95%CI 2.9; 11.7) and in the South and Southeast macro-regions.
conclusionAlthough some healthy indicators have increased, prevalence of ultra-processed food consumption among adolescents is high.
