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
Although highly polar pesticides such as glyphosate (Gly) are widely used and highly relevant for pesticide residue analysis, their analytical determination is still problematic. Methods involving liquid chromatography in combination with tandem mass spectrometry (LC-MS/MS) often lack sensitivity due to insufficient separation from matrix co-extractives causing severe ion suppression effects on Gly and other anionic pesticides. In this study, capillary electrophoresis (CE) was used for an improved separation of analytes from matrix components, thus increasing sensitivity and robustness of analysis. Gly and 13 other anionic pesticides and selected metabolites (including glufosinate, ethephon, fosetyl, phosphonic acid and chlorate) were studied after extraction with the quick polar pesticides (QuPPe) method. Different tests resulted in an improved separation and sensitivity using a background electrolyte (BGE) containing 15% acetic acid and 20% methanol (MeOH) in water. The study also included the investigation of injection conditions and a thorough study of the matrix effects. Finally, results of method validation in several (strawberry, soybean, milk, liver, lemon) matrices of plant and animal origin are presented.
