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
Hydration is the first step in pollen germination. However, the process is not well understood. OsMLO12 is highly expressed in mature pollen grains; plants containing alleles caused by transfer DNA insertions do not produce homozygous progeny. Reciprocal crosses between wild-type and OsMLO12/osmlo12 plants showed that the mutant alleles were not transmitted through the male gametophyte. Microscopic observations revealed that, although mutant grains became mature pollen with three nuclei, they did not germinate in vitro or in vivo due to a failure in hydration. The OsMLO12 protein has seven transmembrane motifs, with an N-terminal extracellular region and a C-terminal cytosolic region. We demonstrated that the C-terminal region mediates a calcium-dependent interaction with calmodulin. Our findings suggest that pollen hydration is regulated by MLO12, possibly through an interaction with calmodulin in the cytosol.
