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
Catabolism of storage reserves and biosynthesis of metabolites necessary for growth are essential for seed germination and establishment. An Arabidopsis (Arabidopsis thaliana) mutant (pkp1) deficient in plastidic pyruvate kinase (PK(p)) and unable to accumulate storage oil to the same extent as the wild type shows delayed germination and seedling establishment dependent on an exogenous sugar supply. It appears, however, as though these phenotypes are not entirely caused specifically by lack of seed oil and may be related to reduced PK(p) activity in germinating seeds. Increasing the sucrose concentration in the medium further inhibits germination of pkp1, possibly due to the accumulation of soluble sugars in seeds. Germinating seeds of pkp1 are unable to metabolize storage oil and cannot utilize applied sucrose for hypocotyl elongation in the dark. Moreover, pkp1 contains less tocopherol and chlorophyll than the wild type. Taken together, the results are consistent with a model in which PK(p) is required for the efficient conversion of sugar into precursors for different anabolic pathways.
