The relationship between energy intake and asthma in Americans aged 1-18 years: a cross-sectional study.

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 effects of total dietary energy intake on asthma. STUDY SELECTION: The study was a retrospective cross-sectional study of Americans aged 1-18 year. Comprehensive demographic, dietary, examination, laboratory, and asthma questionnaire data were collected for each participant. Multivariate logistic regression, restricted triple spline curves, threshold effects, and stratified analyses were used for analysis.
resultsOf 12,090 participants, 1,893 (15.66%) had a diagnosis of asthma. After accounting for potential confounders, compared with the group with the lowest energy intake (Q1), groups 2 (Q2), groups 3 (Q3), and groups 4 (Q4) had adjusted odds ratios (ORs) of 0.72 (0.62-0.85), 0.63 (0.51-0.77) and 0.55 (0.43-0.7) for asthma. The relationship between total energy intake and asthma showed an L-shaped curve (p = 0.001). The results were further verified by stratification and sensitivity analyses. In the threshold analysis, we found that the saturation effect was reached at a total energy intake of 56.442 kcal/kg/day with an OR of 0.981 (0.973-0.989).
conclusionThe prevalence of asthma in Americans aged 1-18 years was associated with total dietary energy intake in an L-shaped curve, with a significant turning point found at approximately 56.442 kcal/kg/day.
