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
objectiveThe objective of this study was to investigate the association between breastfeeding, the introduction of specific foods in the first year of life, and asthma symptoms at 6 years of age.
methodsA longitudinal study was conducted involving 956 children in southern Brazil. Asthma symptoms were assessed through the International Study of Asthma and Allergies in Childhood questionnaire. Information regarding breastfeeding and the introduction of complementary foods during the first year of life was obtained through interviews with mothers conducted at home. A multivariate analysis was performed using Poisson regression, and relative risks were estimated to assess the magnitude of the associations.
resultsAmong the 956 children included in the study, 18.7% exhibited asthma symptoms. Male children had a 3% higher incidence [RR=1.03 (95%CI 1.01-1.06); p=0.023]. Children with a family history of asthma showed a 9% higher incidence [RR=1.09 (1.06-1.13); p<0.001] compared to those without such a history. Nonbreastfed children had an 8% higher incidence [RR=1.08 (95%CI 1.02-1.15); p=0.015]. Moreover, children who were introduced to wheat flour during the first year of life had a 4% higher incidence [RR=1.04 (95%CI 1.01-1.06); p=0.020] of asthma symptoms.
conclusionSignificant and independent associations were observed between asthma symptoms at 6 years of age and male sex, family history of asthma, breastfeeding, and the introduction of wheat flour during the first year of life.
