Safety, tolerability, and immunogenicity of pentavalent meningococcal MenABCWY vaccine in healthy infants: A phase 2b randomized clinical trial.

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
Invasive meningococcal disease is an uncommon but serious disease predominantly affecting children. This phase 2b study evaluated MenABCWY in 6-month-old infants followed by MenB-fHbp and MenABCWY in 2-month-old infants, the latter being the target age and intervention. Participants were randomized to MenABCWY, 60 µg or 120 µg MenB-fHbp+MenACWY-TT, or 4CMenB+MenACWY-TT, administered as 2 primary and 1 booster dose. The primary safety objective was to describe the safety profile of MenABCWY in participants enrolled at 2 months. Primary immunogenicity objectives were the percentage of participants achieving seroprotective serum bactericidal antibody using human complement titers. Overall, 314 and 12 participants were randomized to sentinel cohort and open-label expanded-enrollment stages, respectively. Based on 2 reports of fever requiring invasive investigations and accompanied by cerebrospinal fluid pleocytosis and 1 report arising from a previous study, the Sponsor terminated the study. Local reactions and systemic events after primary vaccination were generally mild to moderate, and tended to be higher with MenABCWY versus 4CMenB+MenACWY-TT. Immunogenicity data suggest that 1 month after vaccination 2, MenABCWY responses for MenA/C/W/Y were robust and comparable with 4CMenB+MenACWY-TT in 2-month-old participants. Immune responses for MenB test strains were higher with MenABCWY versus 4CMenB+MenACWY-TT and generally similar with 60 µg and 120 µg MenB-fHbp+MenACWY-TT or MenABCWY. Based on the limited results, the consistency of MenB immune responses with 60 µg and 120 µg MenB-fHbp suggests doses < 60 µg could be investigated to assess whether a more acceptable safety profile in conjunction with beneficial immune responses is possible in 2-month-old infants.
