Functional Comparison of Short and Long Isoforms of the TRF2 Protein in Drosophila melanogaster.
Article in Doklady. Biochemistry and biophysics, 2019. 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
TRF2 protein (TBP-related factor 2) can substitute for TBP forming alternative transcription initiation complexes on TATA-less promoters, including the promoters of histone H1 and piRNA clusters required for transposon repression. The Drosophilatrf2 gene codes for two isoforms: a "short" and a "long" one, in which the same short TRF2 sequence is preceded by a long N-terminal domain. Here, we demonstrated that the long TFR2 isoform has a greater functional activity than the short isoform by expressing each of them at a reduced rate under the endogenous promoters. Expression of the long isoform alone affects neither the flies' viability nor the sex ratio. Expression of the short isoform alone leads to the phenotype described for the trf2 gene insufficiency and derepression of transposable elements, that is, decreased viability, disturbance of homologous chromosome pairing and segregation, and apparent female-biased sex ratio.
