1 · What the graph read from it

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.

2 · The registry

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

backgroundEarly seizures after craniotomy are significant perioperative complications that can adversely impact patient outcomes. Despite current guidelines advising against the routine use of antiseizure drugs for seizure after craniotomy prevention due to limited efficacy data, many clinicians continue prescribing them. This discrepancy highlights the need for robust evidence to guide clinical practice. This multi-center, randomized clinical trial was designed to investigate the efficacy of perampanel in preventing early seizures after craniotomy.

methodThis multi-center, open-label, randomized clinical trial will be conducted across five hospitals in Nagoya, Japan, from February 2024 to December 2026. A total of 142 seizure-naive patients with supratentorial brain tumors will be recruited and randomized (1:1) into the treatment and control groups. The treatment group will receive 2 mg of perampanel starting 2 days preoperatively and continuing for 28 days postoperatively, while the control group will receive no antiseizure drugs. The primary outcome is the incidence of seizures within 28 days after craniotomy. Secondary outcomes are length of hospital and intensive care unit stays and postoperative complications. DISCUSSION: This study addresses the critical need for evidence-based recommendations regarding antiseizure drug use for preventing early seizures after craniotomy. As the first multi-center, randomized trial evaluating perampanel's efficacy in this setting, the findings may significantly influence clinical guidelines and perioperative practices.

trial registrationThis trial was registered with the Japan Registry of Clinical Trials (approval number: jRCTs041230117) on December 18, 2023, a member of the Primary Registry Network of the World Health Organization's International Clinical Trials Registry Platform.
