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
Adaptive phenotypic plasticity allows organisms to display distinct phenotypes in response to variable environments, but little is known about the genomic changes that promote the evolution of plasticity on a macroevolutionary scale. Here, combining tissue-specific transcriptomics, comparative genomics and genome editing, we show that temperature-mediated plasticity in the size of butterfly eyespot wing patterns, a derived seasonal adaptation estimated to have evolved ~60 million years ago at the base of the satyrid clade (~2,700 extant species), is fuelled by the recruitment of a Hox gene Antennapedia (Antp) to eyespot development. In satyrid butterflies, Antp regulates eyespot size in a temperature-dependent manner, increasing plasticity levels. The cooption of Antp to eyespots was driven by the evolution of a novel eyespot-specific promoter in satyrid genomes, which when disrupted in a model satyrid, Bicyclus anynana, reduced plasticity levels. We show that a taxon-specific cis-regulatory innovation in a conserved developmental gene fuelled the evolution of adaptive phenotypic plasticity across a large clade of animals.
