Extrachromosomal ribosomal DNA of Didymium iridis: sequence analysis of the large subunit ribosomal RNA gene and sub-telomeric region.
Article in Current genetics, 1992. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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 ribosomal DNA of the myxomycete Didymium iridis is organized as extrachromosomal linear molecules of about 20 kb, containing only one transcription unit of the ribosomal RNA genes. We have determined the sequence of the large subunit ribosomal RNA (LSU rRNA) gene as well as the sub-telomeric and telomeric regions. The LSU rRNA gene was found to encode a 3857 nucleotide-long LSU rRNA, interrupted by a transcribed spacer and two group I introns. A complete secondary structure model of D. iridis LSU rRNA has been constructed. The compact sub-telomeric region of D. iridis rDNA was found to contain several directly repeated sequence elements that include the simple telomere motif TTAGGG. Based on pairwise comparisons of LSU rRNA sequences, the time of divergence between the two myxomycete genera Didymium and Physarum was estimated.
