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 vaccinia virus hemagglutinin (HA) is a glycoprotein found on the plasma membrane of infected cells and the envelope of extracellular virus. Two forms of HA (85 and 68 kDa) are detected by immunoblot analysis. Although hemagglutination activity is only readily detectable late in infection, the 85-kDa HA appears early and accumulates throughout infection, whereas the 68-kDa form appears only late in the cycle. Production of the 68-kDa HA but not the 85-kDa HA was inhibited by either cytosine arabinoside or rifampin. Analysis of HA gene expression reveals a complex pattern of expression. The HA gene is transcribed early to yield a 1.65-kb dicistronic early transcript, consisting of the 945-bp HA open reading frame (ORF) fused to a 453-bp downstream ORF. Transcription from this site initiates 7 bases upstream of the AUG initiating codon of the HA ORF. Due to the discrepancy between the calculated size of the HA protein (33 kDa) and that reported for the unglycosylated HA protein derived from in vitro translation (58 kDa), we placed an early transcription termination signal (TTTTTAT) directly downstream of the 945-bp HA ORF. This led to a reduction in size of the early HA mRNA to 1.2 kb, as expected, but had no effect on the formation of either the 85- or 68-kDa protein. Transcripts originating from the early promoter are found throughout the infection cycle. However, after DNA replication, transcription from a second, late promoter ensues. The transcriptional start site of the late promoter is within a consensus TAAATG sequence located 135 bases upstream of the transcriptional start site of the first promoter. The late transcriptional start site is also found within an upstream ORF.
