Immune Development in Early Life (IDEaL) longitudinal cohort study protocol: Identifying biomarkers of vaccine responsiveness, respiratory infection, and asthma.

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
Background: Early-life immune development is a critical factor in predicting the risk of childhood respiratory infections, asthma, and poor vaccine responses. Identifying immune endotypes that predispose children to these conditions could lead to the development of predictive biomarkers and early interventions, potentially improving long-term health outcomes. The IDEaL (Immune Development in Early Life)-Rome prospective pediatric cohort, based at Children's Hospital Bambino Gesù (Rome, Italy), is part of a National Institutes of Health/National Institute of Allergy and Infectious Diseases-supported longitudinal observational study. Objectives: To identify molecular biomarkers associated with increased susceptibility to respiratory infections, asthma, and poor vaccine responsiveness in early childhood. The study aims to establish predictive immune profiles that could guide interventions to redirect harmful immune trajectories. Methods: Mothers are approached during pregnancy prospectively and eligible infants are enrolled at delivery. The study includes 6 planned visits up to 5 years of age. Biosamples (blood, stool, nasal swabs, and cord blood for a subset) were collected at each visit for multiomic data (cytokines, proteomics, microbiome), alongside clinical data on vaccination, infections, and wheezing. Results: The study included 273 participants (100% enrollment completion rate). Over 2 years, clinical and multiomic data were integrated to investigate immune trajectories related to clinical outcomes. Specific data on the outcomes will be provided in future reports as longitudinal analysis continues. Conclusions: The IDEaL-Rome cohort study seeks to identify biomarkers predicting immune development trajectories. These findings could enable early interventions to redirect harmful immune trajectories in infancy and improve health outcomes, though further studies are required to validate biomarkers and refine predictive models for clinical application.
