Efficacy of salvage radiotherapy for relapsed/refractory diffuse large B-cell lymphoma.
Article in Translational cancer research, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundRadiotherapy (RT) is a modality of salvage therapy in relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL), but its efficacy is currently not well defined. This paper reports a retrospective review of patients who received salvage RT for R/R DLBCL in our hospital.
methodsWe selected 32 patients who had relapsed and had progressive disease after chemotherapy or partial remission (PR) after chemotherapy. The patients had a median age of 47 years (range, 13-85 years) and were treated between January 1, 2009, and June 30, 2016. The histological type was DLBCL in all cases. Progression-free survival (PFS) and overall survival (OS) were estimated with the Kaplan-Meier method; predictors for adverse factors were evaluated using a Cox proportional hazards regression model.
resultsMedian age-adjusted International Prognostic Index (IPI) score was 3 (range, 0-4), and 20 (62.5%) patients had large tumors. Patients were irradiated with a median dose of 42.7 Gy (range, 30-54 Gy): 4 (12.5%) by conventional RT, 2 (6.3%) by conformal 3D technique and 26 (81.3%) by intensity-modulated RT (IMRT). Most toxicities were mild (CTCAE grade 1 or 2), including neutropenia, diarrhea, dermatitis, mucositis and dysphagia. With a median follow-up of 25.4 months (range, 0.4-98.9 months) after irradiation, the 5-year PFS and OS were 61.8% and 83.2%, respectively. In multivariate analysis, adverse factors associated with PFS in our cohort were multiple lesions.
conclusionsDue to its low toxicity and ease of use, RT should remain a salvage therapy option for patients with R/R DLBCL.
