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

backgroundEpendymomas are rare primary gliomas that commonly affect both children and adults, but unique as survival is worse in children.

methodsData on brain and central nervous system primary malignant and non-malignant ependymal tumours from the Central Brain Tumor Registry of the United States analytic data set and primary malignant ependymal tumours from the SEER 13 registries research data file were used to evaluate incidence and survival, respectively.

resultsThe 2004-2009 average annual age-adjusted incidence rate of ependymal tumours was 0.41/100,000. Spinal cord/cauda equina was the primary site at diagnosis for 50-60% of ependymal tumours in adult age groups in contrast to about 20% in children and adolescents. Ependymoma was the most frequent histology in all age groups; however, anaplastic ependymoma comprised about 30% in cases 0-19 years of age compared with about 3-5% in adult age groups. Overall, relative survival was favourable with rates at ∼85% and 75% at 3 and 10 years post diagnosis, respectively. However, children and adolescents, the oldest adult age group, cases diagnosed with anaplastic ependymoma and/or tumour location in a brain site had lowest survival rates.

conclusionPaediatric cases had worse outcomes compared with adults for numerous reasons including having a higher percentage of anaplastic ependymomas and greater percentage of cases of intracranial disease.
