Nucleotide sequence and transcriptional studies of the vaccinia virus KpnI I DNA fragment.
Article in Virus genes, 1989. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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 nucleotide sequence of the vaccinia virus (VV) KpnI I DNA fragment has been determined. This central, highly conserved portion of the VV genome corresponds to the right portion of the HindIII E, all of the HindIII O and P, and the left portion of the HindIII I DNA fragments. Computer-assisted analysis of this data indicated the presence of five tandemly oriented, leftward-reading open reading frames (ORFs) I-4, I-3, I-2, I-1, and O-1, with the I-4 ORF being an immediate early gene encoding the large M1 subunit of VV ribonucleotide reductase. Transcriptional analyses suggested that the I-3 and O-1 genes were constitutive genes, being expressed both before and after viral DNA synthesis. The I-1 and I-2 genes were late genes, expressed only after the initiation of viral DNA synthesis. Cell-free translation was used to confirm that the I-3, I-1, and O-1 ORFs were bonafide messages encoding proteins with molecular weights of 30, 35, and 71 kD, respectively. When the predicted amino acid sequences of the proteins encoded by the I-3, I-2, I-1, and O-1 genes were compared to the Genbank data base, no significant alignments were detected. Therefore, the biological functions of these proteins in the VV life cycle remain to be established.
