Protective antibodies against diphtheria, tetanus, and pertussis following revaccination in children and young adults having undergone haematopoietic stem cell transplantation.

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
objectiveHaematopoietic stem cell transplantation (HSCT) eliminates pre-existing immunity, necessitating revaccination. This study aimed to assess the prevalence of protective antibody titres against diphtheria, pertussis, and tetanus in pediatric and young adult HSCT recipients at least four years post-revaccination.
resultsA cross-sectional study was conducted in 94 post-HSCT patients (aged 5-25 years) who completed a three-dose DTP series at least four years prior. Protective anti-tetanus and anti-diphtheria antibody titres were detected in 93.6% and 81.9% of participants, respectively, at least four years post-revaccination. However, only 9.4% had protective anti-pertussis titres, which remained low within five years of revaccination. Factors associated with protective anti-tetanus included higher absolute lymphocyte counts (ALC) 1-year post-revaccination, while corticosteroid use during revaccination was negatively associated. ALC at the 3rd dose of vaccination was associated with a protective anti-diphtheria titre. A booster dose of Tdap resulted in seroconversion in 80.0% for diphtheria, 47.4% for pertussis, and 100% for tetanus. These findings support an earlier booster dose of DTP vaccination in post-HSCT patients.
