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

backgroundThe current standard treatment for glioblastoma (GBM) is maximal safe surgical resection followed by radiation and chemotherapy. Unfortunately, the disease will invariably recur even with the best treatment. Although the literature suggests some advantages in reoperating patients harboring GBM, controversy remains. Here, we asked whether reoperation is an efficacious treatment strategy for GBM, and under which circumstances, it confers a better prognosis.

methodsWe retrospectively reviewed 286 consecutive cases of newly diagnosed GBM in a single university hospital from 2008 to 2015. We evaluated clinical and epidemiological parameters possibly influencing overall survival (OS) by multivariate Cox regression analysis. OS was calculated using the Kaplan-Meier method in patients submitted to one or two surgical procedures. Finally, the survival curves were fitted with the Weibull model, and survival rates at 6, 12, and 24 months were estimated.

resultsThe reoperated group survived significantly longer (

conclusionOur data support the indication of reoperation for GBM, especially for younger patients with good functional status. Under these circumstances, survival can be doubled at 12 and 24 months.
