Role of antiseizure medication in postoperative late seizure and survival among patients with newly diagnosed glioblastoma: A multicenter retrospective study.

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: We conducted a multicenter study to investigate the utility of postoperative antiseizure medication (ASM) in the occurrence of late seizure in glioblastoma. In addition, we analyzed whether postoperative ASM affects survival. Methods: 1132 consecutive patients with newly diagnosed glioblastoma at 39 centers were enrolled. In patients treated with postoperative ASM (levetiracetam [LEV], lacosamide [LCM], or perampanel [PER]), as well as in those who received no medication, the cumulative incidence of late seizure, adverse events, and survival outcomes were analyzed. Results: In total, 1099 patients (female: 482, male: 617, mean age: 67.2 years) were included, among whom, 287 developed postoperative late seizure. The mean onset time of late seizure was 193.6 days after surgery. Postoperative ASMs were administered in 628 cases, LEV in 344, LCM in 124, and PER in 160. The cumulative incidence of late seizure at 12 months was as follows: no medication in 30.9%, LEV in 17.8%, LCM in 28.8%, and PER in 16.2%. Multivariable analysis disclosed that LEV and PER displayed significantly lower cumulative incidences of postoperative late seizure compared with no medication and LCM. By contrast, median progression-free survival/overall survival did not significantly differ among ASMs. However, during the 12-24 month interval, the PER group demonstrated a more favorable prognosis than the other groups. Conclusions: LEV and PER after glioblastoma surgery were associated with a reduced risk of late seizure compared with LCM or no medication. LEV or PER may be considered as postoperative ASMs to optimize seizure control and potentially help preserve patients' QOL.
