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
The plant-specific transcription factor ABSCISIC ACID INSENSITIVE3 (ABI3) or the maize ortholog VIVIPAROUS1 (VP1) is known to regulate seed maturation and germination in concert with the phytohormone abscisic acid (ABA) but is also evolutionarily conserved among land plants including non-seed plants. An ABI3/VP1 ortholog (PpABI3A) from the moss Physcomitrella patens can activate ABA-responsive gene promoters in the moss and angiosperms; however, it failed to fully complement the phenotypes of the Arabidopsis abi3-6 mutant, suggesting that some aspects of ABI3/VP1 functions have diverged during the evolution of land plants. To gain insights into the evolution of ABI3/VP1 function, we performed a comparative analysis of the regulatory elements required for ABI3 activation in Physcomitrella using a wheat Em gene promoter, which is induced by ABA and ABI3/VP1 both in Physcomitrella and in angiosperms. Elimination of either the ACGT core motif in the ABA response element (ABRE) or the RY element, to which ABI3/VP1 binds directly, resulted in a drastic reduction of the ABA response in Physcomitrella. Arabidopsis ABI3 could effectively activate the Em promoter either in an ABRE- or RY-dependent manner, as observed in angiosperms. On the other hand, PpABI3A failed to activate an Em promoter lacking the RY element but not the ABRE. These results suggest that RY-mediated transcriptional regulation of ABI3/VP1 is evolutionarily conserved between the moss and angiosperms, whereas angiosperm ABI3/VP1 has evolved to activate ABA-inducible promoters via the ABRE sequence independently from the RY element.
