1 · What the graph read from it

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.

2 · The registry

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

Calcium (Ca) functions as a secondary messenger and contributes to plant drought tolerance. This study examined how Ca supplementation influences photosynthetic performance and growth in Glycyrrhiza uralensis seedlings under drought stress. Drought significantly reduced net photosynthetic rate, stomatal conductance, and transpiration rate. Under severe drought, photosynthesis was primarily constrained by non-stomatal limitations, indicating damage to the photosynthetic apparatus. Ca supplementation partially restored gas exchange and alleviated drought-induced photoinhibition by mitigating the decline in maximum PSII efficiency. Drought also reduced growth and root yield (plant height, basal diameter, crown area, root length), whereas Ca supplementation promoted seedling growth and alleviated drought-related damage, thereby enhancing overall drought adaptability. These findings demonstrate that Ca plays a key role in maintaining photosynthetic function and alleviating photodamage under water-limited conditions. Appropriate Ca supplementation may therefore serve as a practical strategy to improve drought tolerance and support the sustainable cultivation of G. uralensis in arid and semi-arid regions.
