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
Myosins are eukaryotic molecular motors moving along actin filaments. Only a small set of myosin classes is present in plants, in which myosins have been found to play a role in cytoplasmic streaming and chloroplast movement. Whereas most studies have been done on green algae, more recent data suggest a role of higher plant myosin at the postcytokinetic cell wall. Here we characterize a loss-of-function mutation for a myosin of plant-specific class XI and demonstrate myosin functions during plant development in Arabidopsis. T-DNA insertion in MYA2 caused pleiotropic effects, including flower sterility and dwarf growth. Elongation of epidermal cells, such as in hypocotyls and anther filaments, was reduced by up to 50% of normal length. This effect on anther filaments is responsible for flower sterility. In the meristems of root tips, it was evident that cell division was delayed and that cell plates were mislocated. Like zwichel, a kinesin-related mutation causing two-branched trichomes, the mya2 knockout causes branching defects, but here the trichomes remained unbranched. Growth was also impaired in pollen tubes and root hairs, cells that are highly dependent on vesicle transport. A failure in vesicle flow could be directly confirmed, because cytoplasmic streaming of vesicles and, more so, of large endoplasmic reticulum-based organelles was slowed. The defect in vesicle trafficking was accompanied by failures in basipetal auxin transport, measured in stem segments of inflorescences. This result strongly suggests a causal link between auxin-dependent processes and the distribution of vesicles and membrane-bound molecules by plant myosin.
