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 cell proliferation process of aerial lateral organs, such as leaves and flowers, is coordinated by complex genetic networks that, in general, converge on the cell cycle. The Arabidopsis thaliana NGATHA (AtNGA) family comprises four members that belong to the B3-type transcription factor superfamily, and has been suggested to be involved in growth and development of aerial lateral organs, although its role in the cell proliferation and expansion processes remains to be resolved in more detail. In order to clarify the role of AtNGAs in lateral organ growth, we took a systematic approach using both the loss- and gain-of-functional mutants of all four members. Our results showed that overexpressors of AtNGA1 to AtNGA4 developed small, narrow lateral organs, whereas the nga1 nga2 nga3 nga4 quadruple mutant produced large, wide lateral organs. We found that cell numbers of the lateral organs were significantly affected: a decrease in overexpressors and, inversely, an increase in the quadruple mutant. Kinematic analyses on leaf growth revealed that, compared with the wild type, the overexpressors displayed a lower activity of cell proliferation and yet the mutant a higher activity. Changes in expression of cell cycle-regulating genes were well in accordance with the cell proliferation activities, establishing that the AtNGA transcription factors act as bona fide negative regulators of the cell proliferation of aerial lateral organs.
