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

Epcoritamab, a CD3 × CD20 bispecific antibody, has been approved as salvage therapy for patients with relapsed/refractory large B-cell lymphoma. However, immunotherapeutic agents have been linked to tumor flare reaction (TFR), which is characterized by rapid tumor proliferation associated with the immune response. This report describes the case of a 71-year-old man with relapsed/refractory diffuse large B-cell lymphoma who developed TFR in the cervical lymph nodes during treatment with epcoritamab. Prompt biopsy upon detection of tumor enlargement led to an accurate diagnosis of TFR and informed therapeutic strategies. Subsequent radiotherapy (RT) effectively controlled local lesions while preserving the systemic immune response, suggesting that RT may be an option to prevent the recurrence and progression of TFR and help to avoid discontinuation of effective therapy.
