Surgical Outcomes of Acute Mastoiditis in Pediatric Patients: A Pediatric Health Information System Study.
Article in Otolaryngology--head and neck surgery : official journal of American Academy of Otolaryngology-Head and Neck Surgery, 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
objectiveTo evaluate outcomes of surgically treated acute mastoiditis (AM) in pediatric patients using the Pediatric Health Information System (PHIS). STUDY
designRetrospective cohort study.
settingPediatric tertiary care centers participating in the PHIS.
methodsChildren aged 0 to 18 years with AM treated from January 1, 2016, to December 31, 2022, were identified using International Classification of Diseases, Tenth Revision, Clinical Modifications (ICD-10) codes and categorized by surgical treatment: mastoidectomy alone, myringotomy with mastoidectomy (MMT), or myringotomy alone. Primary outcomes were length of stay (LOS) and 90-day all-cause readmission. Complicated AM was defined via diagnosis codes indicating disease extension beyond the middle ear/mastoid. Multivariable regression models adjusting for patient and hospital-level variables assessed associations. Cohort validation was performed through chart review.
resultsAmong 1368 patients, 637 (46.6%) underwent myringotomy alone, 153 (11.2%) mastoidectomy alone, and 578 (42.3%) MMT. Complicated AM was present in 62.3%, most frequently in patients receiving mastoidectomy alone (76.5%) or MMT (77.9%). Median LOS was longer in the mastoidectomy group (5 days) compared to MMT (4 days) and myringotomy alone (3 days; P < .0001). In adjusted models, mastoidectomy (incident rate ratio [IRR]: 1.20, 95% CI: 1.07-1.34) and MMT (IRR: 1.10, 95% CI: 1.02-1.18) were associated with longer LOS. Ninety-day readmissions occurred in 9.3% of patients, highest in the mastoidectomy group (14.4%; P = .027). Intensive care unit (ICU) admission (adjusted odds ratio [aOR]: 3.98, 95% CI: 2.34-6.77), hematologic/immunologic conditions (aOR: 3.17, 95% CI: 1.85-5.43), and malignancy (aOR: 7.94, 95% CI: 3.91-16.12) were predictors of readmission.
conclusionThis multi-institutional study shows that surgical approach and disease severity correlate with pediatric AM outcomes. Findings support using validated administrative data in studying AM outcomes, addressing limitations of prior literature.
