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
backgroundMango (Mangifera indica L.) is a globally important fruit crop, but its sensitivity to salt stress poses a serious threat to its sustainable cultivation. Salt stress impairs mango growth through osmotic imbalance, ion toxicity, oxidative damage, and reduced nutrient uptake. This study examined the biochemical, physiological, vegetative, and reproductive responses of the Egyptian mango cultivar 'Ewais' under constant salinity stress reflecting the naturally saline irrigation water in the orchard. The research specifically aimed to evaluate the efficacy of polyethylene glycol (PEG) and proline in mitigating the adverse effects of salt exposure. Nine treatments were tested over two consecutive growing seasons (2023 and 2024). The treatments consisted of PEG applied individually at 15 mM (T
resultsThe treatments investigated revealed significant improvements in relative water content (RWC), membrane stability index (MSI), peroxidase (POD) and polyphenol oxidase (PPO) activities, chlorophyll concentration, ascorbate accumulation, proline concentration, total soluble sugar metabolism, and the hormonal balance of indole-3-acetic acid (IAA) and abscisic acid (ABA). Also, positive responses were observed in vegetative growth traits such as shoot elongation, number of flushes, and leaf area, as well as in reproductive traits including fruit set percentage, average fruit weight, and yield. Specifically, the combined treatments of PEG and proline, T
conclusionThe findings support a dual-action mechanism in which PEG triggers osmotic signalling, while proline contributes to maintaining antioxidant defences and metabolic stability, thereby establishing PEG-proline co-application as a promising strategy for enhancing mango productivity under saline conditions.
