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

purposeCentral nervous system tumors are the most common solid tumors in the pediatric population. As children with central nervous system (CNS) tumors are surviving into adolescence and adulthood, more research is being focused on the long-term cognitive outcomes of the survivors. This review examines the literature on different cognitive outcomes of survivors of different childhood posterior fossa CNS tumor types.

methodsThe authors reviewed the literature for articles published from 2000 to 2012 about long-term neuropsychological outcomes of children diagnosed with posterior fossa brain tumors before the age of 18, which distinguished between histological tumor types, and had a minimum follow-up of 3 years.

resultsThe literature search returned 13 articles, and a descriptive analysis was performed comparing intelligence quotient (IQ), attention/executive function, and memory components of 456 survivors of childhood posterior fossa tumors. Four articles directly compared astrocytoma and medulloblastoma survivors and showed medulloblastoma survivors fared worse in IQ, attention/executive function, and memory measurements. Five articles reporting medulloblastomas found IQ, attention, and memory scores to be significantly below the standardized means. Articles examining astrocytoma survivors found IQ scores within the normal range for the population. Survivors of ependymomas reported 2/23 survivors impaired on IQ scores, while a second study reported a significant number of ependymoma survivors lower than the expected population norm.

conclusionsTumor histopathology and the type of postoperative adjuvant therapy seem to have a significant impact on the long-term neuropsychological complications of pediatric posterior fossa CNS tumor survivors. Age at diagnosis and treatment factors are important variables that affect the outcomes of the survivors.
