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

To evaluate the safety and efficacy of postoperative proton beam therapy (PBT) combined with nimustine hydrochloride (ACNU) or temozolomide (TMZ) for glioblastoma multiforme (GBM). The subjects were 46 patients with GBM who were treated with high dose (96.6 GyE) PBT. There were 24 males and 22 females, and the median age was 58 years old (range 24-76). The Karnofsky performance status was 60, 70, 80, 90 and 100 in 5, 10, 12, 11 and 8 patients, respectively. Total resection, partial resection, and biopsy were performed for 31, 14 and 1 patients, respectively. Photon beams were delivered to high intensity areas on T2-weighted magnetic resonance imaging (MRI) in the morning (50.4 Gy in 28 fractions). More than 6 h later, PBT was delivered to the enhanced area plus a 10 mm margin in the first half of the protocol (23.1 GyE in 14 fractions) and to the enhanced volume in the second half (23.1 GyE in 14 fraction). Concurrent chemotherapy with ACNU during weeks 1 and 4 or daily TMZ was administered in 23 and 23 patients, respectively. The overall 1 and 2 year survival rates were 82.6 and 47.6 %, respectively. Median survival was 21.1 months (95 % CI 13.1-29.2), with no significant difference in survival between the ACNU and TMZ groups. The patient characteristics were similar in the two groups. Late radiation necrosis occurred in 11 patients (six ACNU, five TMZ), but was controlled by necrotomy and therapy including bevacizumab. PBT concurrent with ACNU or TMZ was tolerable and beneficial for carefully selected patients with GBM.
