Age-Dependent Impact of Concomitant Radio-Chemotherapy and MGMT Promotor Methylation on PFS and OS in Patients with IDH Wild-Type Glioblastoma: The Real-Life Data.
Article in Cancers, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Biological but not chronological age plus performance have more impact on decision making in glioblastoma patients. We investigated how progression-free survival (PFS) and overall survival (OS) in older patients with IDH wild-type glioblastoma were influenced by concomitant radio-chemotherapy and MGMT promotor methylation status in real-life settings. In total, 142 out of 273 (52%) evaluated patients were older than 65 years, and 77 (55%) of them received concomitant radio-chemotherapy. In senior patients, the initiation of concomitant radio-chemotherapy was associated with significantly better PFS: 15.3 months (CI95: 11.7−18.9) vs. 7.0 months (CI95: 4.3−9.6; p = 0.002). The favorable influence on PFS was not related to MGMT promotor methylation status as it was in the younger cohort. In seniors, concomitant radio-chemotherapy was related to significantly better OS: 20.0 months (CI95: 14.3−26.7) vs. 4.9 months (CI95: 3.5−6.2), p < 0.001. MGMT promotor methylation was related to a more favorable OS only, if concomitant radio-chemotherapy was initiated. In conclusion, more than half of the glioblastoma cohort was older than 65 years of age. Even if PFS and OS were shorter than in the younger cohort, concomitant radio-chemotherapy provided a survival advantage. In real life, MGMT promotor methylation had a positive impact on OS only if the adjuvant therapy was applied.
