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

purposeTo evaluate the overall expression patterns of imprinted genes in human embryonic stem cells following long term culture and differentiation. MATERIALS AND

methodsExpression levels of 65 imprinted genes determined by PCR array were analyzed in one human embryonic stem cell line (cHES1) following prolonged passaging and differentiation.

resultsTranscripts of 63 imprinted genes were detected in cHES1 cells. Expression levels of all but 5 imprinted genes did not correlate with passage numbers or differ in cells after passage 50 compared with those before passage 50. SLC22A2, SLC22A3, CPA, H19, COPG2IT1 and IGF2 expression were significantly increased in embryoid bodies compared with undifferentiated cells.

conclusionsThe global expression profiles of imprinted genes are generally stable in human embryonic stem cells after prolonged passaging and differentiation.
