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

By definition, pseudogenes are relics of former genes that no longer possess biological functions. Operationally, they are identified based on disruptions of open reading frames (ORFs) or presumed losses of promoter activities. Intriguingly, a recent human proteomic study reported peptides encoded by 107 pseudogenes. These peptides may play currently unrecognized physiological roles. Alternatively, they may have resulted from accidental translations of pseudogene transcripts and possess no function. Comparing between human and macaque orthologs, we show that the nonsynonymous to synonymous substitution rate ratio (ω) is significantly smaller for translated pseudogenes than other pseudogenes. In particular, five of 34 translated pseudogenes amenable to evolutionary analysis have ω values significantly lower than 1, indicative of the action of purifying selection. This and other findings demonstrate that some but not all translated pseudogenes have selected functions at the protein level. Hence, neither ORF disruption nor presence of protein product disproves or proves gene functionality at the protein level.
