The translational and transcriptional initiation sites of BmNPV lef-7 gene.
Article in Virus genes, 2006. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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 predicted open reading frame of lef-7 from Bombyx mori nucleopolyhedrovirus (BmNPV) is 45 bp longer at the 5'-terminal and harbors a 42 bp deletion towards the 3' terminal end compared to that of Autograph californica mlulticapsid NPV (AcMNPV). In the present study, to determine whether the BmNPV lef-7 is translated from an initiation site different from that of AcMNPV lef-7, the translational and transcriptional initiation sites of BmNPV lef-7 were examined. A BmNPV mutant, Bmlef7M1(-) was constructed by deleting 11 nucleotides (nt) including the predicted initiation codon ATG. Western blot analysis demonstrated that the size of LEF-7 in BmNPV and Bmlef7M1(-)-infected cells was identical. The LEF-7s in BmNPV and Bmlef7M1(-)-infected cells were both localized in the nuclei as observed using confocal microscopy. Therefore, the presumed initiation codon ATG (at 97059 nt of BmNPV genome) appears to be non-functional for lef-7 translation. The 5'-RACE analysis revealed that transcription of lef-7 mRNA in BmNPV and Bmlef7M1(-)-infected cells both initiated from an ATCATT motif located 26 nt upstream of the second ATG (located at 97014 nt on BmNPV genome), and 20 nt downstream of the presumed initiation codon.
