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

purposeCytogenetic studies of atypical choroid plexus papillomas (CPP) have been poorly described. In the present report, the cytogenetic investigation of an atypical CPP occurring in an infant is detailed.

methodsCPP chromosome preparations were analyzed by giemsa-trypsin-banding (GTG-banding) and comparative genome hybridization (CGH).

resultsConventional karyotype analysis of tumor culture showed a normal chromosome complement. The results were confirmed by CGH, showing normal hybridization patterns for the sample.

conclusionsTo date, the few atypical CPPs described in the literature have shown disparate cytogenetic information. This is the first report of a normal chromosome complement in atypical CPP. The heterogenic genetic features observed in these small series may reflect the diverse genetic background of choroid plexus tumors in children.
