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

backgroundCarmustine wafers (CW) are approved to treat newly or recurrent high-grade gliomas (HGG). Widespread use has been limited regarding some doubtful uncertainties about their efficacy, related increased risk of infection and expensive cost.

objectiveTo describe the epidemiology of CW implantation, search for related complications, long-term survival and associated prognostic factors.

methodsWe processed the French medico-administrative national database to retrieve appropriate cases operated between 2010 and 2018. A survival analysis was conducted.

resultsWe identified 1659 patients treated in 39 institutions. Median age at CW implantation was 61 years and there was an over-representation of male (63.5%). 491 patients (29.6%) had previous diagnosis of glioma. Time between the first surgery and CW implantation was 0.9 years, IQR[0.6, 1.6]. The frontal lobe was the most frequently involved 29%. 131 patients (7.9%) had to be re operated on for a complication of which 121 for surgical site infection. At one year, 514 patients (31%) had died. Median overall survival (OS) was 1.4 years,

conclusionOver the past 9 years, there is a significant decrease utilisation of CW in France. OS after CW implantation is significantly variable as influenced by many factors such as age, gender or recurrent disease but not by post-operative complications. Compare to previous results, CW may increase the OS and this effect seems more pronounced when adjuvant RT/TMZ is given.
