The early dark-response in Arabidopsis thaliana revealed by cDNA microarray analysis.
Article in Plant molecular biology, 2006. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 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
Despite intense research on light responses in plants, the consequences of a simple shift from light to darkness remain poorly characterized. We have examined the transcriptome of Arabidopsis thaliana seedling leaves upon a shift from constant light to darkness for between 1 and 8 h, while excluding most effects associated with circadian oscillation. Expression clustering and gene ontology analyses identified about 790 responsive genes implicated in diverse cellular processes. Compared to the better-studied long-term dark adaptation response, the early response to darkness is partially overlapping yet clearly distinct, encompassing early transient, early sustained, and late response clusters. The repressor of photomorphogenesis, COP1 (constitutive photomorphogenic 1), is not a chief regulator of the early response to darkness, in contrast to its well-established role during long-term dark adaptation and etiolation. Only part of the early dark response can be understood as the opposite of the response following a dark-to-light transition and as a response to sugar deprivation. Bioinformatic comparisons with published microarray datasets further suggest that abscisic acid (ABA) signaling plays a prominent role in the early response to darkness, although this effect is not mediated by an increase in the ABA level. The potential basis for the co-regulation by darkness and ABA is discussed in light of sugar and redox signaling.
