Preclinical signal for a disease-modifying effect on seizure cluster severity with intermittent diazepam treatment.

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
objectiveIn epilepsy, daily treatment provides only symptomatic seizure control, leaving a significant unmet need for a treatment that affects the underlying predisposition to seizures. Here, in a first-of-its-kind study, we test the hypothesis that intermittent treatment of seizure clusters with diazepam in the kainic acid post-status epilepticus rat model of acquired epilepsy has an enduring effect on the seizure cluster phenotype, suggestive of potential disease modification.
methodsFollowing kainic acid-induced status epilepticus, rats with epilepsy were monitored for occurrence of seizure clusters (≥2 seizures in 24 h) for a 3-week baseline period before entering a 6-week treatment period using a previously established multidose regimen of diazepam (n = 7) or vehicle (n = 9) upon identification of a seizure cluster. In a subsequent 2-week outcome period during which no rats received diazepam, we evaluated changes in seizure cluster size, burden (cluster size × severity), duration, and other phenotype parameters.
resultsA total of 3396 seizures and 216 seizure clusters were included for analysis. During the outcome period, time between seizures in a cluster (also interseizure interval [ISI]) was significantly longer in the diazepam group (log ISI = .25 longer, SE = .08, p < .0001), and the proportion of clustered seizures with an ISI of ≤30 min increased in the outcome period in the vehicle group (p = .023) but was stable in the diazepam group. Despite the occurrence of rebound seizures during the treatment period, improvement in several phenotypical parameters, including severity and proportion of seizures in a cluster, supported a positive impact of intermittent diazepam treatment on seizure cluster biology. SIGNIFICANCE: Changes in several seizure cluster phenotypical parameters were suggestive of an enduring disease-modifying effect of diazepam, despite an apparent rebound effect of intermittent diazepam treatment on seizure frequency. Further study is warranted using a model incorporating a background antiseizure medication regimen to potentially attenuate the unexpected rebound seizures.
