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

Rituximab (the chimeric anti-CD20 antibody) is widely used in the treatment of CD20 positive non-Hodgkin's lymphoma (NHL). The response rate at relapse after repeated use in prior CD20 positive responders is lower than 50%. Several mechanisms can be responsible for rituximab resistance. CD20 negative relapses which transformed from CD20 positive aggressive and indolent forms of lymphoma can be the one of the reason of secondary resistance to rituximab. The authors report a case with combination of aggressive and indolent form of lymphoma who relapsed after 7 months from the last dose of rituximab therapy. CD20 transformed negative from positive in her relapsed disease. Patients with CD20 positive B cell NHL must rebiopsy after first line rituximab therapy if their disease relapsed or progressed.
