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

The 5S ribosomal RNA (5S rRNA) is an essential component of ribosomes. Throughout evolution, variation is found among 5S rRNA genes regarding their chromosomal localization, copy number, and intergenic regions. In this report, we describe and compare the gene sequences, motifs, genomic copy number, and chromosomal localization of the Trichomonas vaginalis, Trichomonas tenax, and Tritrichomonas foetus 5S rRNA genes. T. vaginalis and T. foetus have a single type of 5S rRNA-coding region, whereas two types were found in T. tenax. The sequence identities among the three organisms are between 94 and 97%. The intergenic regions are more divergent in sequence and size with characteristic species-specific motifs. The T. foetus 5S rRNA gene has larger and more complex intergenic regions, which contain either an ubiquitin gene or repeated sequences. The 5S rRNA genes were located in Trichomonads chromosomes by fluorescent in situ hybridization.
