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

In an effort to study the molecular basis of the determination processes of the mammalian germ cell lineage, we have tried to isolate a mouse gene homolog to vasa, which plays an essential role as a maternal determining factor for the formation of Drosophila germ cell precursors. By reverse transcriptase PCRs of mouse primordial germ cell cDNAs using family-specific primers, we obtained a gene (Mvh) encoding a DEAD-family protein that showed a much higher degree of similarity with the product of the Drosophila vasa gene (vas) than previously reported mouse genes. In adult tissues, Mvh transcripts were exclusively detected in testicular germ cells, in which Mvh protein was found to be localized in cytoplasm of spermatocytes and round spermatids including a perinuclear granule. The protein was also expressed in germ cells colonized in embryonic gonads but was not detected in pluripotential embryonic cells such as stem cells and germ cells. These results suggest the possibility that the Mvh protein may play an important role in the determination events of mouse germ cells as in the case of Drosophila vasa.
