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
Phosphoenolpyruvate carboxykinase (PEPCK) catalyzes the conversion of oxaloacetate to phosphoenolpyruvate in the gluconeogenic production of sugars from storage oil in germinating oilseeds. Here, we present the results of analysis on PEPCK antisense Arabidopsis plants with a range of enzyme activities from 20% to 80% of wild-type levels. There is a direct correlation between enzyme activity and seedling establishment during early post-germinative growth, thus demonstrating the absolute requirement of PEPCK and gluconeogenesis in this process. Soluble sugar levels in the 35S-PCK1 antisense seedlings are reduced and seedling establishment can be rescued with an exogenous supply of sucrose. We observed an increase in the respiration of acetyl coenzyme A units released from fatty acid beta-oxidation and a corresponding decrease in the production of sugars with decreasing enzyme activity in 2-d-old antisense seedlings. The 35S-PCK1 antisense lines have a more extreme phenotype when compared with Arabidopsis mutants disrupted in the glyoxylate cycle. We conclude that the 35S-PCK1 antisense seedlings are compromised in the ability to use both storage lipid and storage protein through gluconeogenesis to produce soluble sugars.
