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

Six diverse prokaryotic and five eukaryotic genomes were compared to deduce whether the protein synthesis termination signal has common determinants within and across both kingdoms. Four of the six prokaryotic and all of the eukaryotic genomes investigated demonstrated a similar pattern of nucleotide bias both 5' and 3' of the stop codon. A preferred core signal of 4 nt was evident, encompassing the stop codon and the following nucleotide. Codons decoded by hyper-modified tRNAs were over-represented in the region 5' to the stop codon in genes from both kingdoms. The origin of the 3' bias was more variable particularly among the prokaryotic organisms. In both kingdoms, genes with the highest expression index exhibited a strong bias but genes with the lowest expression showed none. Absence of bias in parasitic prokaryotes may reflect an absence of pressure to evolve more efficient translation. Experiments were undertaken to determine if a correlation existed between bias in signal abundance and termination efficiency. In Escherichia coli signal abundance correlated with termination efficiency for UAA and UGA stop codons, but not in mammalian cells. Termination signals that were highly inefficient could be made more efficient by increasing the concentration of the cognate decoding release factor.
