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 hnRNP A1 transcript has a relatively short 5'- untranslated region (UTR) starting with a pyrimidine tract similar to that of mRNAs encoded by the TOP [terminal oligo(pyrimidine)] genes in vertebrates. Such genes code for ribosomal proteins and for other proteins directly or indirectly involved in the production and function of the translation apparatus. As expected from the role of the pyrimidine tract in the translational regulation of TOP mRNAs, the A1 mRNA is more efficiently loaded onto polysomes in growing than in resting cells. On the other hand, a less stringent regulation with respect to that of other TOP mRNAs is observed, partially due to the presence of multiple transcription start sites within the pyrimidine tract, where transcripts with shorter TOP sequences are less sensitive to regulation. Thus, from the point of view of structural features and translation behaviour the A1 mRNA can be included in the class of TOP genes, suggesting a possible role of A1 in translation. Interestingly, a TOP-like behaviour was observed for hnRNP I mRNA but not for hnRNP C1/C2 and A2/B1 mRNAs, indicating the existence of two classes of hnRNPs with different translational regulation.
