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

Translational research has been defined as the scientific study using human material that will ultimately generate patient specific data. A major caveat in human directed study is the availability of high quality and quantities of patient derived homogeneous cells for analysis. Whereas there exist sources for which tumor tissue and blood samples can be made available, the same cannot be said for normal tissue. The absence of normal control tissue has led to the creation of pooled cell lines and tissues for purchase known as "reference RNA". Although initially created for purposes of standardization, the difficulty associated with acquiring normal tissue has led some investigators to use sources of universal pooled RNA for comparative analysis with clinical tissue specimens. In order to study the effects of using Universal Reference RNA on expression profiling experiments we have evaluated the performance of universal RNA compared to RNA obtained from a purified population of colon epithelial cells in defining a set of altered transcripts in colon cancer.
