Impact on survival through consolidation radiotherapy for diffuse large B-cell lymphoma: a comprehensive meta-analysis.
Synthesis in Haematologica, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled 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.
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 has improved response rates and overall survival in B-cell lymphoma (DLBCL). Radiotherapy is an effective treatment modality for lymphomas, but there is uncertainty on its use as consolidation after chemo-immunotherapy mainly in advanced stages. We evaluated its efficacy with a comprehensive meta-analysis and a systematic search of Pubmed, Embase, Cochrane, and abstracts from ASCO, ASH, ESMO and ASTRO published from June 1966 and December 2018. We identified 11 trials that evaluated consolidation radiotherapy following chemotherapy in a randomized fashion in 4'584 patients. The primary endpoint of this meta-analysis was PFS. As three of the eleven trials were retracted, this data is based on 2414 patients. For the primary endpoint (PFS), we found a hazard ratio (HR) of 0.77 (0.51 to 1.17, pooled (tau2: 0.25; I2: 85%), and a HR of 0.80 (0.53 to 1.21, pooled (bivariate meta-analysis). For overall survival, the HR is 0.93 (0.61 to 1.40; pooled (tau2: 0.25; I2: 74%) and 0.86 (0.58 to 1.27) in a bivariate meta-analysis. The lack of benefit did not change over time (p-value: 0.95 (tau2: 0.32; I2: 88%), and was also absent for PFS when stratifying for chemotherapy, the use of Rituximab, age, the dose of radiotherapy, application to patients in complete remission and with bulky disease. None of the trials used a PET-guided approach. This meta-analysis revealed no survival benefit when consolidation radiotherapy is given to unselected DLBCL patients following chemotherapy. These results need to be considered in future trials in the PET-CT era.
