Association between body mass index z-score and hypoxemia during pediatric dental sedation: a retrospective cohort study.
Article in Journal of anesthesia, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeEvidence regarding the effect of body habitus on respiratory safety during pediatric dental sedation remains limited. This study investigated the association between age- and sex-standardized body mass index (BMI) z-score and new-onset intraoperative hypoxemia in children undergoing dental treatment under deep sedation.
methodsWe retrospectively reviewed children aged 2-10 years who underwent comprehensive dental treatment under propofol-ketamine-based deep sedation at a single dental hospital between July 2024 and February 2026. The primary outcome was new-onset intraoperative hypoxemia, defined as a sustained decrease in SpO₂ to <95% for ≥10 s. Multivariable logistic regression was used to evaluate the association between BMI z-score category and hypoxemia.
resultsThe final analysis included 512 children; 273 (53.3%) developed new-onset intraoperative hypoxemia. Compared with normal-weight children, overweight/obese children had higher odds of hypoxemia in the multivariable model (odds ratio [OR] 3.393, 95% confidence interval [CI] 1.596-7.213; p = 0.002). Underweight status was not associated with hypoxemia. Longer procedure duration was also associated with higher odds of hypoxemia (OR 1.116, 95% CI 1.083-1.150; p < 0.001). Ketamine and total propofol doses were not associated with the primary outcome. A post hoc sensitivity analysis using a more stringent definition of hypoxemia (SpO₂ <90%) yielded consistent results.
conclusionOverweight/obese status was independently associated with new-onset intraoperative hypoxemia during pediatric dental sedation. Longer procedure duration also emerged as an associated procedural factor. These findings may support individualized respiratory vigilance in children with increased body mass during shared-airway dental sedation.
