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
In many plants, efflux of organic anions from roots has been proposed as one of the major Al resistance mechanisms. However it remains unknown how plants regulate efflux of organic anions in response to Al. In this study, the regulatory mechanisms of Al-responsive malate efflux in wheat (Triticum aestivum) were characterized focusing on the role of protein phosphorylation. Al-resistant wheat (cv Atlas) initiated malate efflux at 5 min after addition of Al, and this response was sensitive to temperature. K-252a, a broad range inhibitor of protein kinases, effectively blocked the Al-induced malate efflux accompanied with an increased accumulation of Al and intensified Al-induced root growth inhibition. A transient activation of a 48-kD protein kinase and an irreversible repression of a 42-kD protein kinase were observed preceding the initiation of malate efflux, and these changes were canceled by K-252a. Malate efflux was accompanied with a rapid decrease in the contents of organic anions in the root apex, such as citrate, succinate, and malate but with no change in the contents of inorganic anions such as chloride, nitrate, and phosphate. These results suggest that protein phosphorylation is involved in the Al-responsive malate efflux in the wheat root apex and that the organic anion-specific channel might be a terminal target that responds to Al signaling mediated by phosphorylation.
