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

We isolated a novel gene designated mak (male germ cell-associated kinase) by using weak cross-hybridization with a tyrosine kinase gene (v-ros). Sequence analysis of the cDNA corresponding to the 2.6-kilobase transcript revealed that the predicted product of rat mak consisted of 622 amino acids and contained protein kinase consensus motifs in its amino-terminal region. Comparison of the deduced amino acid sequence of mak in the kinase domain with those of other protein kinase genes demonstrated that mak was approximately 40% identical to the cdc2-CDC28 gene family in Schizosaccharomyces pombe, Saccharomyces cerevisiae, and humans but less identical to most other protein kinase gene products. Expression of mak was highly tissue specific, and its transcripts were detected almost exclusively in testicular cells entering and after meiosis but hardly detectable in ovarian cells including oocytes, after the dictyotene stage. These results suggest that the mak gene plays an important role in spermatogenesis.
