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

backgroundPrimary brain tumors are a complex heterogenous group of benign and malignant tumors. Reports on their occurrence in the English population by sex, age, and morphological subtype and on their incidence are currently not available. Using data from the National Cancer Registration and Analysis Service (NCRAS), the incidence of adult primary brain tumor by major subtypes in England will be described.

methodsData on all adult English patients diagnosed with primary brain tumor between 1995 and 2017, excluding spinal, endocrinal, and other CNS tumors, were extracted from NCRAS. Incidence rates were standardized to the 2013 European Standard Population. Results are presented by sex, age, and morphological subtype.

resultsBetween 1995 and 2017, a total of 133 669 cases of adult primary brain tumor were registered in England. Glioblastoma was the most frequent tumor subtype (31.8%), followed by meningioma (27.3%). The age-standardized incidence for glioblastoma increased from 3.27 per 100 000 population per year in 1995 to 7.34 in men in 2013 and from 2.00 to 4.45 in women. Meningioma incidence also increased from 1.89 to 3.41 per 100 000 in men and from 3.40 to 7.46 in women. The incidence of other astrocytic and unclassified brain tumors declined between 1995 and 2007 and remained stable thereafter.

conclusionPart of the increase in the incidence of major subtypes of brain tumors in England could be explained by advances in clinical practice including the adoption of new diagnostic tools, classifications and molecular testing, and improved cancer registration practices.
