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

backgroundSaltwater intrusion is a common threat to coastal agriculture. This study investigated the mitigating and restorative effects of exogenous prohexadionecalcium (Pro-Ca) on rice under simulated saltwater intrusion. Salt-tolerant Chaoyou 1000 and salt-sensitive Huanghuazhan were treated with 100 mg·L⁻¹ Pro-Ca at the four-leaf-one-bud stage. Physiological responses were analyzed during stress (D1–D4) and recovery (FD4).

resultsSalt stress significantly inhibited rice growth, reduced biomass, induced oxidative damage, and impaired photosynthesis and photosystem II (PSII) activity, with maximum damage at D4. Exogenous Pro-Ca enhanced stress tolerance by activating antioxidant enzymes and the ascorbate-glutathione (AsA-GSH) cycle, effectively scavenging reactive oxygen species (ROS) and protecting cell membrane integrity. Additionally, Pro-Ca maintained PSII activity and improved light use efficiency, ensuring photosynthetic function. During recovery (FD4), Pro-Ca-treated plants showed superior physiological recovery compared to salt-stressed controls.

conclusionsThe exogenous application of Pro-Ca effectively alleviates salt stress damage caused by seawater intrusion in rice. It enhances salt tolerance by strengthening the antioxidant defense system and maintaining photosynthetic function, while significantly promoting the recovery of physiological status during the post-stress rehabilitation phase.
