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
Superoxide dismutase (SOD) is believed to enhance abiotic stress resistance by converting superoxide radical (O2 (-)) to H2O2 to lower ROS level and maintain redox homeostasis. ROS level is controlled via biphasic machinery of ROS production and scavenging. However, whether the role of SOD in abiotic stress resistance is achieved through influencing the biophasic machinery is not well documented. Here, we identified a wheat copper-zinc (Cu/Zn) SOD gene, TaSOD2, who was responsive to NaCl and H2O2. TaSOD2 overexpression in wheat and Arabidopsis elevated SOD activities, and enhanced the resistance to salt and oxidative stress. TaSOD2 overexpression reduced H2O2 level but accelerated O2 (-) accumulation. Further, it improved the activities of H2O2 metabolic enzymes, elevated the activity of O2 (-) producer NADPH oxidase (NOX), and promoted the transcription of NOX encoding genes. The inhibition of NOX activity and the mutation of NOX encoding genes both abolished the salt resistance of TaSOD2 overexpression lines. These data indicate that Cu/Zn SOD enhances salt resistance, which is accomplished through modulating redox homeostasis via promoting NOX activity.
