Chitosan mitigates water stress in cowpea plants through modulation of growth, homeostasis, and antioxidant activities.

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: Climate change and population growth increase food demand, especially in semi-arid regions. Water deficit affects cowpea productivity, but foliar application of chitosan can improve its tolerance, stimulating antioxidant activity and growth. This study analyzed chitosan application in cowpea (cv. BRS Olhonegro) under different irrigation levels, seeking alternatives to enhance productivity. Methods: The experiment was conducted in a growth chamber using a completely randomized design. Three concentrations of chitosan (0, 50, and 75 mg L Results: At the V5 development stage, the 50 mg L Discussion: In summary, chitosan application mitigated the adverse effects of water stress in cowpea by maintaining water balance, preserving photosynthetic pigments, enhancing antioxidant mechanisms, and providing osmoprotection to the crop. This study highlights chitosan's potential as a cost-effective and environmentally friendly strategy to increase cowpea resilience to drought, an essential crop for food security in semi-arid regions.
