Effective Protection Against Status Epilepticus Caused by Lithium-Pilocarpine: Combination of Midazolam and Lacosamide.
Article in Brain and behavior, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
aimStatus epilepticus causes the most severe condition related to epilepsy in terms of high mortality rate. Although status epilepticus treatment guidelines specify a treatment process based on three-stage monotherapy, effective control cannot yet be achieved in all cases. In the presented study, with electrophysiological and behavioral tests, it was aimed to investigate the effectiveness of the combination of midazolam (MDZ), one of the most commonly used benzodiazepines in the first-line treatment of status epilepticus, with the second-line antiepileptics levetiracetam (LEV), lacosamide (LCM), valproic acid (VPA), and fosphenytoin (fPHT).
methodsA status epilepticus model was created with lithium-pilocarpine (5 mEq/kg-320 mg/kg) in adult male Sprague-Dawley rats with implanted electroencephalography (EEG) electrodes. MDZ (9 mg/kg) alone or in dual combinations with antiepileptic drugs (200 mg/kg LEV, 50 mg/kg LCM, 300 mg/kg VPA, 100 mg/kg fPHT) was injected i.p. to the experiment groups with status epilepticus. After video-EEG recordings were taken from the rats during and after status, the effects of drug interactions on cognitive and motor behaviors were examined by applying behavioral tests (open field, Rotarod, radial arm maze, and passive avoidance).
resultsCompared with the untreated status epilepticus group, it was determined that MDZ alone and the combination of four antiepileptic drugs administered with MDZ significantly reduced the mortality rate, spike frequency, and spike amplitude of epileptic seizures and suppressed epileptic seizures at certain levels (p < 0.01). Compared to MDZ monotherapy, it was determined that the mortality rate and spike frequency and amplitude decreased significantly in the MDZ + LCM group (p < 0.01), whereas on the other hand, mortality and spike frequency increased in the MDZ + LEV group (p < 0.01). No negative effects were observed in learning and memory in all treatment groups, but it was determined that the motor functions of the animals treated with MDZ + fPHT were impaired compared to both the control group without any treatment and the MDZ group (p < 0.01).
conclusionIn the status epilepticus model induced by lithium-pilocarpine, the combination of MDZ + LCM was found to be the most effective polytherapy option in reducing seizures and mortality. Additionally, it was observed that LEV, LCM, and VPA administered together with MDZ did not negatively affect both cognitive and motor functions.
