High transposition rates of Osvaldo, a new Drosophila buzzatii retrotransposon.
Article in Molecular & general genetics : MGG, 1994. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 16 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
Transposition of a new Drosophila retrotransposon was investigated. Total genomic Southern analysis and polytene in situ hybridizations in D. buzzatii strains and other related species using a 6 kb D. buzzatii clone (cDb314) showed a dispersed, repetitive DNA pattern, suggesting that this clone contains a transposable element (TE). We have sequenced the cDb314 clone and demonstrated that it contains all the conserved protein sequences and motifs typical of retrovirus-related sequences. Although cDb314 does not include the complete TE, the protein sequence alignment demonstrates that it includes a defective copy of a new long terminal repeat (LTR) retrotransposon, related to the gypsy family, which we have named Osvaldo. Using a D. buzzatii inbred line in which all insertion sites are known, we have measured Osvaldo transposition rates in hybrids between this D. buzzatii line and its sibling species D. koepferae. The results show that Osvaldo transposes in bursts at high rate, both in the D. buzzatii inbred line and in species hybrids.
