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

Current treatment strategies in patients with newly-diagnosed glioblastoma include surgical resection with post-operative radiotherapy and concomitant/adjuvant temozolomide (the "Stupp protocol") or resection with implantation of 1,3-bis(2-chloroethyl)-1-nitrosourea (BCNU) wafers in the surgical cavity followed by radiotherapy. In clinical practice, patients with malignant glioma treated with BCNU wafer often also receive adjuvant temozolomide. However, current treatment guidelines are unclear on whether and how these treatment practices can be combined, and no prospective phase 3 study has assessed the safety and efficacy of combining BCNU wafers with temozolomide and radiation in high-grade malignant glioma. The rationale for multimodal therapy comprising surgical resection with adjunct local BCNU wafers followed by radiotherapy and temozolomide is based on complementary and synergistic mechanisms of action between BCNU and temozolomide in preclinical studies; a shared primary resistance pathway, methylguanine-DNA methyltransferase (MGMT); and the opportunity to overcome resistance through MGMT depletion to boost cytotoxic activity. A comprehensive review of the literature identified 19 retrospective and prospective studies investigating the use of this multimodal strategy. Median overall survival in 14 studies of newly-diagnosed patients suggested a modest improvement versus resection followed by Stupp protocol or resection with BCNU wafers, with an acceptable and manageable safety profile.
