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
backgroundThe circadian clock controls several important processes in plant development, including the phase transition from vegetative growth to flowering. In Arabidopsis thaliana, the circadian-regulated gene CONSTANS (CO) plays a central role in the photoperiodic control of the floral transition, one of the most conserved flowering responses among distantly related plants. CO is a member of a plant-specific family of transcription factors, and when it arose during the evolution of higher plants is unclear.
resultsA CO homologous gene present in the genome of the unicellular green alga Chlamydomonas reinhardtii (CrCO) can complement the Arabidopsis co mutation and promote early flowering in wild-type plants when expressed under different promoters. Transcript levels of FLOWERING LOCUS T (FT), the main target of CO, are increased in CrCO transgenic plants in a way similar to those in plants overexpressing CO. In the microalga, expression of CrCO is influenced by day length and the circadian clock, being higher in short photoperiods. Reduction of CrCO expression in Chlamydomonas by RNA interference induces defects in culture growth, whereas algae induced to express high levels of CrCO show alterations in several circadian output processes, such as starch accumulation and the onset of expression of genes that regulate the cell cycle.
conclusionsThe effects observed may reflect a conserved role for CrCO in the coordination of processes regulated by photoperiod and the circadian clock. Our data indicate that CO orthologs probably represent ancient regulators of photoperiod-dependent events and that these regulators arose early in the evolutionary lineage that gave rise to flowering plants.
