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

aim of the studyThe extensive neovascularisation of malignant glioma is mainly influenced by vascular endothelial growth factor (VEGF). The effect of ZD6474, a potent inhibitor of VEGF-receptor-2, was evaluated in combination with either radiotherapy or temozolomide.

methodsThe effects on glioma growth were investigated in the intracerebral BT4C rat glioma model. ZD6474 30 mg/kg was given alone or in combination with radiotherapy 12 Gy x 1 or with temozolomide 100 mg/kg for 3 days. Two different experiments were performed comparing ZD6474 to radiotherapy or temozolomide. For each experiment 28 animals were randomized into four groups.

resultsZD6474 in combination with radiotherapy significantly decreased tumour area by 66% compared with controls whereas the combination with temozolomide decreased tumour area by 74%.

conclusionsZD6474 in combination with two standard modalities in the treatment of malignant glioma, radiotherapy and chemotherapy, markedly decreased the growth of an intracerebral experimental glioma. These results justify further investigations of these therapies in combination.
