1 · What the graph read from 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.

2 · The registry

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

backgroundThe use of alkylating chemotherapy versus bevacizumab for recurrent glioblastoma remains controversial. Here, we tested the hypothesis that the activity of alkylators, but not that of bevacizumab, would be associated with the O

methodsWe analyzed a cohort of patients treated at centers of the German Glioma Network or the University Hospital Zurich with alkylating agent-based chemotherapy (n = 260) or bevacizumab without or with irinotecan (n = 84) for first recurrence of glioblastoma. Outcome was stratified for O

resultsMedian post-recurrence survival-1 (PRS-1) for patients receiving alkylating agents at first recurrence was longer than with bevacizumab (11.1 versus 7.4 months, p < 0.001). The use of alkylators was associated with longer PRS-1 for patients with a methylated versus unmethylated MGMT promoter (p = 0.017). For patients receiving bevacizumab, PRS-1 was not different with or without MGMT promoter methylation. PRS-1 was longer in patients receiving alkylating chemotherapy compared to bevacizumab for patients with methylated (p < 0.001) or unmethylated MGMT promoter (p = 0.034). For patients with alkylators at first recurrence receiving bevacizumab at any further recurrence, PRS-1 was longer than in patients receiving bevacizumab first and alkylators thereafter (p = 0.002).

conclusionsThis study confirms limited value of bevacizumab in recurrent glioblastoma independent of MGMT status. Alkylating agents have activity in recurrent glioblastoma, especially in the context of MGMT promoter methylation.
