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

The boundaries between indolent neoplastic and reactive lymphoproliferations were discussed during the 2024 European Association for Haematopathology/Society for Hematopathology workshop in Dubrovnik, Croatia. Session 4 focused on the revision of indolent pediatric lymphoid neoplasms/lymphoproliferations. Forty-one cases were submitted, representing good examples of indolent pediatric lymphomas/lymphoproliferations and their diagnostic challenges. The morphologic spectrum of pediatric-type follicular lymphoma (PTFL) was discussed, especially exploring unifying features of cases with and without marginal zone differentiation (MZD) (the first also referred to as pediatric nodal marginal zone lymphoma). Unusual features like relapses/recurrences; extranodal involvement and high proliferation rate in the marginal zone differentiated component were observed in PTFL with or without MZD. Rare follicle center-derived neoplasms occurring in children other than PTFL where discussed, such as primary testicular follicular lymphoma and follicle center lymphoma of the lower female genital tract. Testicular follicular lymphomas were compared to cases known from literature, defining a better picture of their clinicopathological features. The criteria for the diagnosis of atypical lymphoid hyperplasia were reviewed and nodal and extranodal cases are discussed. Plasmacytic proliferations in the pediatric population are exceedingly rare, but do exist in clonal and non-clonal forms. A heterogeneous group of extranodal lymphomas is included, among them extranodal marginal zone lymphomas (MZL) of the stomach with a large cell transformation and an intramuscular MZL with comparable features of a cutaneous MZL/lymphoproliferation with IgG4 expression. In this report, the different spectrum of indolent pediatric lymphomas compared to the adult counterpart will be highlighted, to avoid misdiagnosis and overtreatment.
