Prophylactic use of antiepileptics in spontaneous intracerebral hemorrhage: a systematic review and meta-analysis focusing on early seizures and clinical determinants.

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 and purposeSeizures are a common complication after spontaneous intracerebral hemorrhage (SICH), but whether prophylactic anti-seizure medications (ASMs) reduce early seizures (≤ 7 days post-SICH) remains unclear. Moreover, the factors influencing clinicians' decisions regarding prophylactic ASMs are poorly characterized. This systematic review and meta-analysis aimed to determine whether prophylactic ASMs reduce early seizures after SICH, to evaluate their effects on late seizures and functional outcomes, and to identify patient characteristics associated with prophylactic ASMs use.
methodsThe Pubmed, Embase and Cochrane database were searched for studies comparing prophylactic ASMs use versus no prophylaxis in adult patients with SICH. The primary outcomes were early seizures and late seizures. Secondary outcomes included mortality and modified Rankin Scale score (mRS) ≥ 3 at the longest follow-up. Pooled odds ratios (OR) with 95% confidence intervals (CI) were calculated using random-effects models.
resultA total of 22 studies comprising 8288 patients were included. Prophylactic ASMs use significantly reduced the risk of early seizures (OR, 0.39; 95% CI 0.20-0.76, p = 0.006, I
conclusionProphylactic ASMs are effective in preventing early seizures after SICH but do not reduce late seizures or improve long-term functional outcomes. Clinicians selectively target prophylaxis to patients with lobar hemorrhage or those undergoing surgery, reflecting guideline-permitted flexibility for high-risk subgroups.
