DmOAZ, the unique Drosophila melanogaster OAZ homologue is involved in posterior spiracle development.
Article in Development genes and evolution, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
In this paper, we study DmOAZ, the unique Drosophila melanogaster homologue of the OAZ zinc finger protein family. We show partial conservation of the zinc finger organization between DmOAZ and the vertebrate members of this family. We determine the exon/intron structure of the dmOAZ gene and deduce its open reading frame. Reverse transcriptase-polymerase chain reaction analysis shows that dmOAZ is transcribed throughout life. In the embryo, strongest DmOAZ expression is observed in the posterior spiracles. We suggest that dmOAZ acts as a secondary target of the Abd-B gene in posterior spiracle development, downstream of cut and ems. In a newly created loss-of-function mutant, dmOAZ ( 93 ), the "filzkörper" part of the posterior spiracles, is indeed structurally abnormal. The dmOAZ ( 93 ) mutant is a larval lethal, a phenotype that may be linked to the spiracular defect. Given the dmOAZ ( 93 ) mutant as a new tool, the fruit fly may provide an alternative model for analyzing in vivo the functions of OAZ family members.
