Efficacy and Tolerability of Adjunctive Brivaracetam in Patients with Focal-Onset Seizures on Specific Concomitant Antiseizure Medications: Pooled Analysis of Double-Blind, Placebo-Controlled Trials.
Trial report in Advances in therapy, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to 3 registered trials, which are not on this map. Cited by 2 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.

Abstract
introductionThis article aimed to assess the efficacy and tolerability of adjunctive brivaracetam (BRV) in adults with focal-onset seizures on specific concomitant antiseizure medications (ASMs) taken as part of their treatment regimen.
methodsThis was a post hoc analysis of pooled data from double-blind, placebo-controlled trials (N01252/NCT00490035, N01253/NCT00464269, and N01358/NCT01261325) in patients with uncontrolled focal-onset seizures randomized to BRV (50-200 mg/day) or placebo on the most common concomitant ASMs at trial initiation.
resultsNine concomitant ASMs were analyzed: carbamazepine (CBZ), lamotrigine (LTG), valproate (VPA), oxcarbazepine (OXC), topiramate (TPM), phenytoin (PHT), lacosamide (LCM), clobazam (CLB), and phenobarbital (PHB). Reduction over placebo in focal-onset seizure frequency per 28 days with BRV ranged from 11.7% (concomitant OXC) to 33.5% (concomitant PHB). The median percentage reduction from baseline in focal-onset seizure frequency per 28 days ranged from 25.5% to 42.8% in patients on BRV (placebo 4.4-21.2%); 50% responder rates ranged from 31.9% to 44.9% in patients on BRV (placebo 11.4-25.2%). In patients on BRV, seizure freedom ranged from 1.4% (concomitant PHT) to 12.5% (concomitant LCM); seizure freedom ranged from 0% to 1.2% in patients on placebo. All efficacy endpoints analyzed were consistently numerically higher in patients on BRV versus placebo. The overall incidence of treatment-emergent adverse events (TEAEs) was generally similar across subgroups by specific concomitant ASMs in patients on BRV (range 60.8-74.5%) or placebo (range 53.8-66.7%). Drug-related TEAEs were numerically higher across all subgroups by concomitant ASM in patients on BRV (range 35.2-48.3%) versus placebo (range 23.9-37.1%). Discontinuations due to TEAEs ranged from 2.9% to 13.3% in patients on BRV and was 0-5.7% for patients taking placebo across subgroups.
conclusionBRV was efficacious and well tolerated regardless of the specific concomitant ASMs used as part of their treatment regimen. These data show that in patients with focal-onset seizures, BRV provides additional efficacy to a broad range of ASMs.
