Rice transgenic plants with suppressed expression of the β subunit of the heterotrimeric G protein.
Article in Plant signaling & behavior, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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 deficient mutant for the rice heterotrimeric G protein α subunit gene (RGA1), d1, showed dwarfism and set small seed due to a reduced cell number. Mutants for the rice heterotrimeric G protein β subunit gene (RGB1) have not been isolated. To determine the functions of RGB1, transgenic rice plants with suppressed expression of RGB1 were studied using the RNAi method. RGB1 knock-down lines showed browning of the lamina joint regions and nodes and reduced fertility, but these abnormality were not observed in d1. Transgenic plants in which the G protein β subunit was greatly decreased were not obtained, suggesting that the complete suppression of RGB1 mRNA may be lethal. In contrast, the d1 mutants, with complete loss of the G protein α subunit, were fertile and half the size of the WT. These studies suggest that RGB1 has different functions than RGA1.
