Intracranial pressure trajectories and functional outcomes in pediatric intracranial hemorrhage: a group-based trajectory modeling analysis.
Article in European journal of pediatrics, 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
Monitoring the dynamic changes in intracranial pressure (ICP) is crucial for assessing clinical outcomes in pediatric intracranial hemorrhage (ICH). However, the ICP trajectory patterns remain unknown. We aim to identify distinct ICP trajectory patterns in pediatric ICH and assess their impact on clinical outcomes. Pediatric ICH population were enrolled in Jiangsu Pediatric Medical Center. We utilized group-based trajectory modeling (GBTM) to identify distinct hourly ICP trajectories from the initiation of ICP monitoring up to the fourth day. The ΔICP was calculated to capture short-term fluctuations in ICP. Both the ICP trajectory patterns and ΔICP values were analyzed to assess ICP dynamics. Clinical characteristics were compared across the identified trajectory groups to explore potential differences. Multivariable logistic regression analyses were performed to investigate their associations with six-month functional outcomes, with adjustment for potential confounders. A total of 201 eligible patients were included in the study. GBTM identified five distinct ICP trajectories, which differed significantly in terms of mechanical ventilation, vasoactive agent use, pupil reactivity, craniectomy, initial, maximum, and median ICP, as well as ΔICP variability, Glasgow Coma Scale (GCS), and six-month Pediatric Glasgow Outcome Scale-Extended (pGOSE) scores. Compared with the "Low-Stable" group, patients in the "High-Fluctuating" and "Mid-Range Stable with Variability" groups had significantly higher odds of poor six-month outcomes (OR 24.28, 95% CI 2.91-202.90; OR 9.02, 95% CI 1.76-46.35, respectively).
conclusionsThis study reveals substantial heterogeneity in ICP trajectories among children with ICH and identifies three patterns associated with poor neurologic outcomes. Characterizing dynamic ICP trajectory subtypes may assist in early risk stratification and provide insight into ICP regulation patterns. WHAT IS KNOWN: • Intracranial pressure (ICP) levels are linked to outcomes in pediatric intracranial hemorrhage (ICH). • Current understanding is based on static ICP measurements rather than longitudinal patterns. WHAT IS NEW: • This study identifies five distinct ICP trajectory subtypes using group-based trajectory modeling. • Three dynamic ICP patterns are significantly associated with poor 6-month neurologic outcomes.
