Persistent Atelectasis Prevalence and Incidence in Pediatric Critical Care.
Article in Cureus, 2025. 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 and objective In critical care, persistent atelectasis worries pediatricians. The research on hospitalized pediatric patients with persistent atelectasis reports limited data about prevalence and incidence. The study aimed to determine the prevalence and incidence of persistent atelectasis in pediatrics. Methodology and materials This retrospective observational study was carried out in the pediatric intensive care unit (PICU) of King Fahad Medical City (KFMC) between February 2020 and October 2023. Pediatric patients with pulmonary atelectasis for more than 48 hours. Patients who were admitted to the PICU were taken into the study and evaluated after taking informed consent. Patients who were prescribed dornase alfa for atelectasis treatment. The prevalence and incidence of the disease were calculated in both treatment groups; independent t-tests and chi-square tests were used to compare continuous and categorical variables, respectively, between the dornase and non-dornase groups. Correlation analysis was performed using Pearson's correlation coefficient to examine relationships between clinical parameters. Regression analysis was conducted to identify significant predictors of intensive care unit (ICU) length of stay and persistent atelectasis, with model significance evaluated using the F-statistic and R² values. A p-value < 0.05 was considered statistically significant for all analyses. Results The prevalence of persistent atelectasis reached 48.18% among patients who received dornase, while the non-dornase group experienced 51.82% atelectasis occurrence. The incidence analysis demonstrated a major distinction between groups where dornase-treated patients experienced 26.4 new at-risk patient cases but non-dornase-treated patients developed 71.5 new cases. Conclusion The dornase treatment group demonstrates the potential to decrease new persistent atelectasis incidence in pediatric critical care units. The non-dornase group showed slightly higher persistent atelectasis prevalence and incidence rates yet dornase treatment seemed to prevent atelectasis progression in pediatric patients at risk. The research demonstrates dornase's ability to prevent atelectasis occurrence yet its effect on patient overall survival remained concerning because of the retrospective study design. Future researchers are encouraged to do studies that help to establish a causal relationship between dornase alfa and persistent atelectasis occurrence.
