Use of rituximab in mature, high-grade and advanced-stage pediatric B-lineage non-Hodgkin lymphomas: a systematic review, meta-analysis and the Brazilian reality.

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
Objectives: Rituximab is a valuable agent for treating adult B-cell non-Hodgkin lymphoma (B-NHL), and several studies have tested its efficacy in children with mature, high-grade B-NHL. The aim of the present study was to systematically review the use of rituximab in children and adolescents with high-grade mature B-NHL and to conduct a meta-analysis of the evidence. Since access to this medication in public health systems in low- and middle-income countries is complex, we were also interested in mapping access to it in Brazil. Methods: We conducted a systematic review and meta-analysis on the survival of pediatric patients with mature, high-grade and advanced-stage B-NHL treated with rituximab in combination with chemotherapy in first-line treatment or later. Patients' access to the medication was evaluated through a questionnaire sent to oncologists in Brazilian pediatric oncology centers. Results: We selected 17 trials, which were subsequently grouped by disease type and line of therapy. In patients receiving first-line treatment, excluding those with primary mediastinal B-cell lymphoma (PMBL), the use of rituximab resulted in (1) better event-free survival [Hazard Ratio of 0.37 (0.22, 0.61); Conclusion: Rituximab improves outcomes in pediatric patients receiving first-line treatment for high-grade B-NHL (except PBML) and overall survival in R/R patients. However, access to rituximab in Brazilian hospitals is currently dependent on centers supporting its economic burden.
