DDB2, DDB1A and DET1 exhibit complex interactions during Arabidopsis development.
Article in Genetics, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 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
Damaged DNA-binding proteins 1 and 2 (DDB1 and DDB2) are subunits of the damaged DNA-binding protein complex (DDB). DDB1 is also found in the same complex as DE-ETIOLATED 1 (DET1), a negative regulator of light-mediated responses in plants. Arabidopsis has two DDB1 homologs, DDB1A and DDB1B. ddb1a single mutants have no visible phenotype while ddb1b mutants are lethal. We have identified a partial loss-of-function allele of DDB2. To understand the genetic interaction among DDB2, DDB1A, and DET1 during Arabidopsis light signaling, we generated single, double, and triple mutants. det1 ddb2 partially enhances the short hypocotyl and suppresses the high anthocyanin content of dark-grown det1 and suppresses the low chlorophyll content, early flowering time (days), and small rosette diameter of light-grown det1. No significant differences were observed between det1 ddb1a and det1 ddb1a ddb2 in rosette diameter, dark hypocotyl length, and anthocyanin content, suggesting that these are DDB1A-dependent phenotypes. In contrast, det1 ddb1a ddb2 showed higher chlorophyll content and later flowering time than det1 ddb1a, indicating that these are DDB1A-independent phenotypes. We propose that the DDB1A-dependent phenotypes indicate a competition between DDB2- and DET1-containing complexes for available DDB1A, while, for DDB1A-independent phenotypes, DDB1B is able to fulfill this role.
