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

Nonsense-mediated mRNA decay (NMD) is a translation-coupled mechanism that eliminates mRNAs containing premature translation-termination codons (PTCs). In mammalian cells, NMD is also linked to pre-mRNA splicing, as in many instances strong mRNA reduction occurs only when the PTC is located upstream of an intron. It is proposed that in these systems, the exon junction complex (EJC) mediates the link between splicing and NMD. Recent studies have questioned the role of splicing and the EJC in initiating NMD. Instead, they put forward a general and evolutionarily conserved mechanism in which the main regulator of NMD is the distance between a PTC and the poly(A) tail of an mRNA. Here we discuss the limitations of the new NMD model and the EJC concept; we argue that neither satisfactorily accounts for all of the available data and offer a new model to test in future studies.
