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

introductionGlioblastoma multiforme (GBM) is the most common primary brain tumour in adults. Although the survival rate for GBM has improved with recent advancements in treatment, the prognosis remains generally poor.

methodsWe conducted a retrospective review of GBM patients seen in National University Hospital, Singapore, and Tan Tock Seng Hospital, Singapore, from January 2002 to December 2011. Data on disease and treatment factors was collected and correlated with survival.

resultsData on a total of 107 GBM patients was analysed. Their median survival time was 15.1 months and the two-year survival rate was 23.5%, which is comparable with data published in other series. The factors associated with improved median survival time were radiotherapy dose > 50 Gy (16.1 months vs. 8.7 months, p = 0.01) and adjuvant concurrent chemotherapy (16.4 months vs. 9.2 months, p = 0.003).

conclusionGBM confers a poor prognosis. Adjuvant radiotherapy and chemotherapy are associated with improved survival. Ethnicity may be a contributing factor to differences in GBM incidence and prognosis.
