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
We describe the structure, organization, and transcriptional impact of repetitive elements within the lignin-degrading basidiomycete, Phanerochaete chrysosporium. Searches of the P. chrysosporium genome revealed five copies of pce1, a ~1,750-nt non-autonomous, class II element. Alleles encoding a putative glucosyltransferase and a cytochrome P450 harbor pce insertions and produce incomplete transcripts. Class I elements included pcret1, an intact 8.14-kb gypsy-like retrotransposon inserted within a member of the multicopper oxidase gene family. Additionally, we describe a complex insertion of nested transposons within another putative cytochrome P450 gene. The disrupted allele lies within a cluster of >14 genes, all of which encode family 64 cytochrome P450s. Components of the insertion include a disjoint copia-like element, pcret3, the pol domain of a second retroelement, pcret2, and a duplication of an extended ORF of unknown function. As in the case of the pce elements, pcret1 and pcret2/3 insertions are confined to single alleles, transcripts of which are truncated. The corresponding wild-type alleles are apparently unaffected. In aggregate, P. chrysosporium harbors a complex array of repetitive elements, at least five of which directly influence expression of genes within families of structurally related sequences.
