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
backgroundCr stress represents a major threat to ecosystem sustainability, crop productivity, and human health. Tre is a non-reducing sugar with significant potential to alleviate abiotic stress toxicity. However, its role in mitigating Cr toxicity via seed priming remains poorly understood. METHODOLOGY: Therefore, this study evaluated the effects of Tre priming on alleviating Cr toxicity in two barley cultivars, Sultan-17 and Haider-93, exposed to three Cr levels (0, 20, and 40 mg kg⁻¹ soil) and three seed priming treatments (hydropriming, 10 mM Tre, and 15 mM Tre).
resultsCr stress at 40 mg kg⁻¹ reduced growth and yield in both cultivars, an effect associated with increased oxidative damage and Cr accumulation in plant organs, along with decline in photosynthetic pigments, water content, nutrient uptake, and synthesis of IAA and GA. Tre seed priming notably alleviated these detrimental effects. Specifically, under 40 mg kg⁻¹ Cr stress, 15 mM Tre priming increased biological yield by 58% and 90%, and grain yield by 23.9% and 44.7% in Sultan-17 and Haider-93, respectively, relative to the non-primed controls. These improvements were associated with reduced levels of H₂O₂ (27.6% and 41.7%), MDA (28.5% and 46.2%), and ABA (21.2% and 22.9%); enhanced nutrient accumulation; increased CAT (9.1% and 9.2%) and POD (20.1% and 25.1%) activities; and higher ascorbic acid (14.5% and 10.7%) and APX (15.2% and 26.6%) levels. Furthermore, compared with non-primed controls, Tre priming improved osmotic balance, as reflected by increases in TSP (1.8% and 5.4%), FAA (27% and 34.8%), secondary metabolites, and endogenous Tre synthesis (31.5% and 31%) under Cr stress. These physiological adjustments contributed to enhanced biological and grain yields in both cultivars.
conclusionCollectively, these findings position Tre priming as an effective and economical strategy for improving Cr tolerance and crop production in Cr-contaminated soils, providing a base for developing eco-friendly approaches to ensure safer food production in polluted environments.
