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

purposeThe aim of this study was to investigate the role of platelet-derived growth factor (PDGF) and PDGF receptors (PDGFRs) in the proliferation of human glioblastoma cells as a prerequisite for a new therapeutic approach to the treatment of malignant brain tumors with selective tyrosine kinase inhibitors such as imatinib. METHODS AND

resultsIn the human glioblastoma cell lines U-87 MG, U-118 MG and U-373 MG different PDGF and PDGFR mRNAs were detected by RT-PCR, and the expression of the receptor proteins was demonstrated by immunostaining and flow cytometry. Moreover, functional activity of PDGFRs was demonstrated in PDGFRbeta expressing glioblastoma cell variants by measuring the mobilization of intracellular Ca(2+) upon PDGF-BB stimulation. However, addition of PDGF-BB to the serum-free culture medium had no stimulatory effect on cell proliferation. Furthermore, cell growth in serum-supplemented and serum-free medium was not affected by imatinib, leflunomide and AG-1296 at therapeutically relevant concentrations.

conclusionOur results suggest that clinical antitumor effects of imatinib on glioblastoma, if any, are not mediated by the PDGFR.
