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 5' untranslated region of poliovirus type 2 Lansing RNA consists of 744 nucleotides containing seven AUG codons which are followed by in-frame termination codons, thus forming short open reading frames (ORFs). To determine the biological significance of these small ORFs, all of the upstream AUG codons were mutated to UUG. The point mutations were introduced into an infectious poliovirus cDNA clone, and RNA transcribed in vitro from the altered cDNA was transfected into HeLa cells to recover the virus. Mutation of AUG 7 resulted in a virus (called R2-5NC-14) with a small-plaque phenotype, whereas mutation of the other six AUG codons produced virus with a wild-type plaque morphology. To determine whether the small-plaque phenotype of R2-5NC-14 was due to altered translational efficiency of the viral mRNA, we constructed chimeric mRNAs containing the 5' noncoding region of poliovirus mRNA fused to the chloramphenicol acetyltransferase (CAT) coding sequence. mRNA containing a mutated AUG 7 codon showed decreased translational efficiency in vitro. The results indicate that the upstream ORFs of poliovirus RNA are not essential for viral replication and do not act as barriers to the translation of poliovirus mRNA. AUG 7 and flanking sequences may play a positive acting role in poliovirus RNA translation.
