1 · What the graph read from it

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.

2 · The registry

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

abstractEpstein-Barr virus (EBV) infection is associated with ∼1.5% of human tumors, including B-cell lymphoproliferative diseases (LPDs). A common approach to treating EBV-associated LPDs is targeting infected tumor cells with a CD20 monoclonal antibody, such as rituximab, although this often fails to prevent relapses and refractory disease. In this study, we show using a preclinical humanized mouse model the superior efficacy of a CD3×CD20 bispecific T-cell engager in preventing systemic virus spread and EBV-associated tumor formation, compared with rituximab treatment. This increased efficacy is associated with a deep depletion of human precursor B cells in the bone marrow. Progenitor B cells are permissive to infection with EBV in vitro and correlate with EBV persistence during B-cell depletion therapy, also in vivo. Thus, deep depletion of B cells, including bone marrow progenitors, might target EBV-associated LPDs more efficiently. Infected progenitors should be considered an EBV reservoir from which associated pathologies could relapse.
