Prevalence of pediatric delirium among critically ill children: a meta-analysis of observational studies.
Synthesis in Frontiers in pediatrics, 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
Background: Pediatric delirium (PD) is a serious neurological complication in critically ill children, associated with prolonged hospitalization, extended mechanical ventilation, and increased mortality. However, the pooled prevalence of PD in this population remains unclear. This meta-analysis of observational studies aimed to determine the overall prevalence of PD among critically ill children and to identify its potential moderating factors. Methods: A comprehensive literature search was conducted in PubMed, Web of Science, Scopus, Embase, Cochrane Library, and CINAHL from inception to May 26, 2026. Methodological quality was appraised with the Joanna Briggs Institute (JBI) critical appraisal checklist for prevalence studies. Pooled prevalence of PD was calculated utilizing a DerSimonian-Laird random-effects model. To stabilize variances and improve the normal approximation, a logit transformation was applied for the meta-analysis of prevalence data. Heterogeneity was assessed using Cochran's Results: This meta-analysis included 40 observational studies, involving 18,875 critically ill children. The pooled prevalence of PD among critically ill children was 38.1% (95% CI: 32.5-43.8%, I Conclusions: Our findings indicate that PD is a prevalent neurological complication among critically ill children. However, due to extremely high heterogeneity and a very wide prediction interval, this pooled estimate should not be interpreted as a stable universal figure, but merely as a summary of highly heterogeneous studies. Therefore, caution is warranted when generalizing the pooled estimate to local settings. Systematic Review Registration: identifier CRD420261339560.
