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

backgroundCentral nervous system (CNS) atypical teratoid/rhabdoid tumors (AT/RT) are aggressive tumors usually diagnosed in young children and characterized by SMARCB1 (INI1, hSNF5) gene abnormalities. Despite initial chemo-radiation responsiveness, most children die of progressive disease (PD). Little data regarding familial AT/RT clinical course exist. This study described and compared familial (F) versus sporadic (S) AT/RT and elucidated SMARCB1 mutations and inheritance patterns.

methodsA retrospective chart review, pedigree, and SMARCB1 analysis were done.

resultsBetween January 1989 and June 2009, 20 children with CNS AT/RT were diagnosed, 8-S and 12-F. Median age at diagnosis (months) of S and F patient were: 13 and 4.8, respectively. Median survival (months) was S-21, F4.5, and 8-all. Pedigree analyses showed unaffected parent carriers with multiple affected offspring.

conclusionsChildren with F-AT/RT are younger, have more extensive disease, and are more likely to die from PD than children with S-AT/RT. Surgery, radiation, and chemotherapy were important in achieving long-term survival. Pedigree analysis supports autosomal dominant inheritance pattern with incomplete penetrance. Germline SMARCB1 mutation analysis is important in all patients diagnosed with AT/RT to (1) determine actual incidence of F-AT/RT, (2) determine penetrance of predisposing mutations, (3) provide appropriate genetic counseling, and (4) establish surveillance screening guidelines.
