Development and validation of the HIGHT prediction model for early hematoma expansion in spontaneous intracerebral hemorrhage.
Article in Scientific reports, 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
Spontaneous intracerebral hemorrhage (sICH) is associated with high mortality and disability, with early hematoma expansion (EHE) being a key factor in poor prognosis. The most effective strategies for predicting EHE and improving patient outcomes remain unclear. This study systematically reviewed clinical studies on EHE in sICH from the PubMed database (2013-2023) to identify key predictors for a prediction model. Key factors included: Hematoma hypodensity, Island sign, Glasgow Coma Scale, Hematoma in ventricular, and Taking anticoagulant(H-I-G-H-T). The HIGHT model was developed based on these predictors and validated using receiver operating characteristic (ROC) curves, calibration curves, and decision curve analysis. A dynamic nomogram (DN) was created for clinical use. Results: The model was tested in a retrospective cohort of 532 patients, yielding a good fit (AUC = 0.706, P < 0.0001). In a prospective cohort of 83 patients, the AUC was 0.642 (P = 0.048), with sensitivity of 93.75% and specificity of 32.84%.Conclusion: The HIGHT prediction model demonstrated It has shown a certain extent predictive effectiveness in both retrospective and prospective evaluations. And the online DN is now available for clinical use.
