Germinal-center type B-cell classification and clinical characteristics of Chinese pediatric diffuse large B-cell lymphoma: a report of 76 cases.

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
Pediatric diffuse large B-cell lymphoma (DLBCL) is a highly aggressive disease with unique clinical characteristics. This study analyzed the germinal-center type B-cell (GCB) classification and clinical characteristics of Chinese pediatric DLBCL. A total of 76 patients with DLBCL newly diagnosed in Sun Yat-sen University Cancer Center between February 2000 and May 2011, with an age younger than 18 years, were included in the analysis. The male/female ratio was 3.47:1. The median age was 12 years (range, 2 to 18 years), and 47 (61.8%) patients were at least 10 years old. Of the 76 patients, 48 (63.2%) had stage III/IV disease, 9 (11.8%) had bone marrow involvement, 1 (1.3%) had central nervous system (CNS) involvement, and 5 (6.6%) had bone involvement. The GCB classification was assessed in 45 patients: 26 (57.8%) were classified as GCB subtype, and 19 (42.2%) were classified as non-GCB subtype. The modified B-NHL-BFM-90/95 regimen was administered to 50 patients, and the 4-year event-free survival (EFS) rate was 85.8%. Among these 50 patients, 31 were assessed for the GCB classification: 17 (54.8%) were classified as GCB subtype, with a 4-year EFS rate of 88.2%; 14 (45.2%) were classified as non-GCB subtype, with a 4-year EFS rate of 92.9%. Our data indicate that bone marrow involvement and stage III/IV disease are common in Chinese pediatric DLBCL patients, whereas the percentage of patients with the GCB subtype is similar to that of patients with the non-GCB subtype. The modified B-NHL-BFM-90/95 protocol is an active and effective treatment protocol for Chinese pediatric patients with DLBCL.
