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: Early prognostic assessment after intracerebral hemorrhage (ICH) relies mainly on neurological severity and neuroimaging features. Whether routinely available inflammatory-coagulation biomarkers provide meaningful incremental information beyond these established predictors remains uncertain. Objective: To develop and internally validate an admission-based nomogram incorporating inflammatory-coagulation biomarkers for predicting 90-day poor functional outcome in patients with deep hypertension-related ICH. Methods: This single-center retrospective cohort study included consecutive patients with deep hypertension-related ICH admitted between January 2020 and December 2025. Poor functional outcome was defined as a 90-day modified Rankin Scale score of 4-6. Candidate predictors available within 24 hours of admission were evaluated using least absolute shrinkage and selection operator logistic regression followed by multivariable logistic regression. Model performance was assessed using discrimination, calibration, Brier score, bootstrap internal validation, reclassification metrics, and decision curve analysis. Results: Among 462 patients, 162 (35.1%) had poor functional outcome. The final model retained age, Glasgow Coma Scale score, hematoma volume, intraventricular hemorrhage, admission blood glucose, neutrophil-to-lymphocyte ratio, and ln(D-dimer). Adding NLR and ln(D-dimer) increased the AUC from 0.765 to 0.828 (P = 0.008), representing a statistically significant but modest absolute improvement of 0.063, and reduced the Brier score from 0.178 to 0.142. The optimism-corrected AUC was 0.816. Decision curve analysis showed greater net benefit than the conventional model across threshold probabilities of 15%-65%. Sensitivity analyses yielded consistent biomarker associations and model performance. Conclusion: Adding NLR and D-dimer to established clinical-imaging predictors provided a modest improvement in 90-day outcome prediction in deep hypertension-related ICH. These biomarkers may offer complementary prognostic information, but the clinical importance of this incremental gain remains to be established. External validation is required before broader clinical application.
