Re-irradiation for recurrent glioblastoma multiforme: a critical comparison of different concepts.
Article in Strahlentherapie und Onkologie : Organ der Deutschen Rontgengesellschaft ... [et al], 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 papers, 2 of them syntheses 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
purposePurpose of this study was to investigate outcome and toxicity of re-irradiation for recurrent primary glioblastoma (rGBM). We evaluated a group of patients with rGBM and identical primary treatment comprising adjuvant radiotherapy (30 × 2 Gy) with concurrent temozolomide (TMZ).
methodsIn this retrospective study of 46 patients, all received adjuvant or definitive normofractionated radiotherapy to a pretreated area, some with concurrent chemotherapy. Impact of different clinical, histological, or epidemiological factors on survival and radiation toxicity was reviewed.
resultsOf 46 patients, 40 completed the intended therapy. Overall survival (OS) was 20 months (range 6-72 months). Overall survival and progression-free survival after re-irradiation (OS2 and PFS2) were 9.5 and 3.4 months (range 2-40 and 0.7-44 months). Simultaneous systemic therapy improved PFS2 and OS2 (4.3 vs. 2.0, p < 0.001 and 12 vs. 4 months, p = 0.13, respectively). Therapy with TMZ or bevacizumab improved PFS2 vs. nitrosureas (6.6 vs. 2.9, p = 0.03 and 5.1 vs. 2.9 months, p = 0.035, respectively). TMZ also improved PFS2 and OS2 vs. all other systemic therapies (6.6 vs. 4, p < 0.001 and 17 vs. 10 months, p = 0.1). In a subgroup analysis for patients with methylation of the MGMT promoter, doses of >36 Gy as well as TMZ vs. no systemic therapy improved PFS2 (p = 0.045 and p = 0.03, respectively). 27.5% of all patients had no acute toxicity. Three patients with acute and four patients with late grade 3 toxicities were reported.
conclusionNormofractionated radiotherapy is a feasible option for rGBM with a good toxicity profile. Simultaneously applied systemic therapy was associated with improved outcome. For MGMT promoter-methylated histology, higher radiation doses improved survival.
