Antibody Responses to Meningococcal Vaccine in Hematopoietic Cell Transplant Recipients with Veno-Occlusive Disease Treated with Eculizumab.
Article in Infection & chemotherapy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Treatment with eculizumab increases the risk of invasive meningococcal infection (IMI). We evaluated tetravalent meningococcal vaccine responses in pediatric hematopoietic cell transplant (HCT) recipients with eculizumab for veno-occlusive disease (eculizumab group, n=4) and compared to patients with asplenia/polysplenia (asplenia/polysplenia group, n=2). Among the eculizumab group, two patients had a partial and full antibody response, respectively; two had no response. In contrast, the asplenia/polysplenia group showed full responses. These findings suggest poor vaccine response in HCT patients receiving eculizumab during the early post-HCT period, indicating limited meningococcal vaccine response and a need for antibiotic prophylaxis to prevent IMI in this group.
