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
objectiveThe use of anticoagulants to prevent deep vein thrombosis (DVT) after intracerebral hemorrhage (ICH) remains controversial. This study aims to evaluate the safety of anticoagulants in preventing DVT in patients with ICH.
methodsData were sourced from the Chinese Stroke Center Alliance. The primary outcomes include in-hospital mortality, intracranial hematoma evacuation, and hematoma expansion. Absolute standardized differences (ASD) are used to assess differences between groups, and multivariate logistic regression analysis is employed to analyze correlations. Platelet counts and international normalized ratio (INR) were examined within subgroups. Propensity score matching (PSM) is used for sensitivity analysis.
resultsA total of 56,633 patients with ICH were finally enrolled. Multivariate logistic regression analysis revealed that anticoagulant use correlated with reduced in-hospital mortality and hematoma expansion (OR: 0.59, 95% CI: 0.50-0.69, p < 0.001 and OR: 0.55, 95% CI: 0.41-0.73, p < 0.001), while no association was observed with intracranial hematoma evacuation clearance (OR: 1.00, 95% CI: 0.93-1.08, p = 0.941). Subgroup analysis revealed an increased risk of intracranial hematoma evacuation with anticoagulant use when INR >1.7 (OR: 1.47, 95% CI: 1.15-1.89, p = 0.002), but not of in-hospital mortality (OR: 1.20, 95% CI: 0.78-1.85, p = 0.409) or hematoma expansion (OR: 0.66, 95% CI: 0.19-2.25, p = 0.503). PSM yielded consistent outcomes.
conclusionsPost-ICH anticoagulant therapy to prevent DVT is safe, posing no heightened risk of in-hospital mortality, intracranial hematoma evacuation, or hematoma expansion. However, caution is warranted in patients with coagulopathies.
