Efficacy of preoxygenation by spontaneous tidal volume breathing for 3 minutes in pediatric patients aged 0-6 years: a prospective observational 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
Background: Effective preoxygenation is critical for preventing hypoxemia during airway management, particularly in infants and young children who are physiologically more vulnerable. Although the standard practice of administering 100% oxygen via face mask for at least 3 minutes is adapted from adult protocols, supporting evidence in young children remains limited. This study aimed to evaluate the efficacy of standard 3-minute tidal volume breathing preoxygenation in achieving a fractional expired oxygen concentration (FeO Methods: This prospective observational study included children aged 0-6 years undergoing elective surgery under general anesthesia. Exclusion criteria included baseline oxygen saturation <95%, preoperative oxygen supplementation, pulmonary disease, and overweight status. Sedation was administered using with intravenous fentanyl and midazolam. The primary outcomes were the proportion of patients achieving FeO Results: A total of 126 patients were included in the analysis. The FeO Conclusions: Standard preoxygenation with 100% oxygen for 3 minutes is effective in achieving an FeO
