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 support of the hypothesis of the endosymbiotic origin of eukaryotes, much evidence has been found to support the idea that some organelles of eukaryotic cells originated from bacterial ancestors. Less attention has been paid to the identity of the host cell, although some biochemical and molecular genetic properties shared by archaea and eukaryotes have been documented. Through comparing 507 taxa of 16S-18S rDNA and 347 taxa of 23S-28S rDNA, we found that archaea and eukaryotes share twenty-six nucleotides signatures in ribosomal DNA. These signatures exist in all living eukaryotic organisms, whether protist, green plant, fungus, or animal. This evidence explicitly supports the archaeal origin of eukaryotes. In the ribosomal RNA, besides A2058 in Escherichia coli vs. G2400 in Saccharomyces cerevisiae, there still exist other twenties of sites, in which the bases are kingdom-specific. Some of these sites concentrate in the peptidyl transferase centre (PTC) of the 23S-28S rRNA. The results suggest potential key sites to explain the kingdom-specific spectra of drug resistance of ribosomes.
