Efficacy and Safety of RelabotulinumtoxinA, a New Ready-to-Use Liquid Formulation Botulinum Toxin: Results From the READY-1 Double-Blind, Randomized, Placebo-Controlled Phase 3 Trial in Glabellar Lines.
Trial report in Aesthetic surgery journal, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 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
backgroundRelabotulinumtoxinA (RelaBoNT-A, Galderma, Uppsala, Sweden) is an innovative, ready-to-use liquid botulinum toxin A, produced with PEARL (precipitation-free extraction and activity-preserving refined liquid) manufacturing technology, which yields a potent, complex-free formulation.
objectivesIn the READY-1 study, efficacy and safety outcomes following a single RelaBoNT-A treatment for glabellar line correction were examined.
methodsAdults with moderate to severe glabellar lines received RelaBoNT-A (50 U) or placebo in a 3:1 randomized, 6-month, phase 3, multicenter, double-blind study. Primary endpoints (examined at Month 1, maximum frown) comprised the composite ≥2-grade response, defined as ≥2-grades improvement from baseline on concurrent investigator (glabellar line investigator live assessment; GL-ILA) and participant (glabellar line subject live assessment; GL-SLA) severity scales (US endpoint), and the investigator-reported responder rate for participants scored as 0 (none) or 1 (mild) (GL-ILA scale only; EU endpoint). Participant satisfaction and treatment-emergent adverse events (TEAEs) were reported.
resultsOverall, 297 adults were randomized and treated. Month 1 composite ≥2-grade responder rate was 82.9% (RelaBoNT-A, n = 199) vs 0% (placebo, n = 67; P < .001). Month 1 investigator-reported none or mild responder rate was 96.3% (RelaBoNT-A) vs 4.5% (placebo; P < .001). GL-ILA scores remained higher with RelaBoNT-A (23.6% [none or mild]; 58.1% [≥1-grade improvement]) vs placebo (1.5%; 10.4%, respectively) through Month 6 (P < .001). In the Kaplan-Meier analysis, 75% still showed GL-ILA and GL-SLA improvements from baseline at 169 days (end of study). Participants reported onset of effect from Day 1 (39%) and satisfaction with natural-looking results (96.8%; Month 1). RelaBoNT-A-related TEAEs were low (3.6%) and typically mild.
conclusionsA single RelaBoNT-A treatment was effective and demonstrated a favorable safety profile. RelaBoNT-A provided significant improvements in glabellar line severity, high satisfaction, rapid onset, and enduring effectiveness throughout the 6-month study period. LEVEL OF EVIDENCE: 1:
