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
Introduction: In Brazil, maize is commonly cultivated during the off-season (fall/winter), a period characterized by reduced rainfall that substantially limits crop productivity. Foliar application of nutrients and amino acids has emerged as a promising strategy to mitigate physiological damage caused by water deficit by enhancing plant tolerance to abiotic stress. However, the combined effects of magnesium (Mg) and amino acids (AA) on off-season maize have not yet been investigated. Methods: A field experiment was conducted to evaluate the effects of foliar applications of Mg and AA on the photosynthetic and antioxidant metabolism of off-season maize. Four treatments were evaluated: (I) control, (II) foliar application of Mg, (III) foliar application of AA, and (IV) combined foliar application of Mg and AA (Mg+AA). Leaf nutritional status, photosynthetic traits, antioxidant enzyme activity, and grain yield were assessed. Results: The combined Mg+AA treatment improved leaf nutritional status, photosynthetic performance, enzymatic activity, and antioxidant metabolism compared with the isolated applications of Mg or AA. Grain yield increased by approximately 15% under Mg+AA relative to the control, whereas isolated applications of AA and Mg increased yield by 10% and 5%, respectively. Discussion: The results demonstrate additive effects of Mg and AA on the photosynthetic and antioxidant metabolism of maize plants. The combined foliar application of Mg and AA effectively alleviated stress effects and enhanced grain yield, representing a promising strategy to improve the productivity of off-season maize under field conditions.
