Attenuation value of non-contrast computed tomography for spontaneous intracerebral hemorrhage: an important marker for the rapid identification of hematoma expansion.

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
Objective: Patients with spontaneous intracerebral hemorrhage (sICH) are highly prone to early hematoma expansion (HE). However, current limitations in the ability to quantify hematoma density restrict the prediction of HE risk. This study investigated whether relative CT attenuation value can predict HE in patients with sICH. Methods: This study included patients with sICH treated between January 1, 2020, and December 31, 2023. All patients underwent a baseline CT scan within 24 h of symptom onset and a follow-up CT scan within 36 h. The critical threshold for HE prediction based on the relative CT attenuation value was determined by plotting receiver operating characteristic (ROC) curves. Results: Of the 351 patients with sICH included in this study, 91 (25.9%) exhibited HE. After adjusting for confounding factors, multivariate logistic regression analysis indicated that the relative CT attenuation value could independently predict HE ( Conclusion: Relative CT attenuation value of hematoma can independently predict HE in patients with sICH.
