4CMenB Breadth of Immune Response, Immunogenicity, and Safety: Results From a Phase 3 Randomized, Controlled, Observer Blind Study in Adolescents and Young Adults.
Trial report in Open forum infectious diseases, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Background: Meningococcal serogroup B (MenB) strains are highly diverse. Breadth of immune response for the MenB vaccine, 4CMenB, administered at 0-2, 0-6, or 0-2-6 months, was demonstrated by endogenous complement-human serum bactericidal antibody (enc-hSBA) assay against an epidemiologically relevant panel of 110 MenB strains. Methods: In a phase 3 trial, 3651 healthy 10- to 25-year-old participants were randomized 5:5:9:1 to receive 4CMenB (0-6 schedule), 4CMenB (0-2-6 schedule), investigational MenABCWY vaccine, or control MenACWY-CRM vaccine. The primary objectives were to evaluate safety and demonstrate breadth of immune response by enc-hSBA assay against the MenB strain panel using test-based (percentage of samples without bactericidal activity against strains after 4CMenB vs control vaccination) and responder-based (percentage of participants whose postvaccination sera kill ≥70% strains) approaches. Success was demonstrated with 2-sided 97.5% confidence interval (CI) lower limit >65%. Immunogenicity was assessed by traditional hSBA assay against four indicator strains. Results: Breadth of immune response (test-based) was 78.7% (97.5% CI, 77.2-80.1), 81.8% (80.4-83.1), 83.2% (81.9-84.4) for the 0-2, 0-6, and 0-2-6 schedules, respectively, and (responder-based) 84.8% (81.8-87.5), 89.8% (87.2-92.0), and 93.4% (91.2-95.2), respectively. No clinically relevant differences in immunogenicity were observed across schedules. 4CMenB was well tolerated. Conclusions: The 2-dose (0-2, 0-6) 4CMenB schedules met predefined criteria for success for both breadth of immune response endpoints against a diverse MenB strain panel, had comparable immunogenicity, and safety in line with the established 4CMenB safety profile. The 3-dose schedule provided no additional immunological benefit, supporting use of the 4CMenB 0-2 schedule.
