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
This study evaluated the effects of double nanoemulsions of saffron petal extract (DN-SPE), stabilized with soybean (SPI) and pea protein isolates (PPI), alone or combined with Lepidium sativum L. seed gum (LSG) (SL or PL), on the quality and shelf life of ricotta cheese during refrigerated storage (4 ± 0.5 °C). In vitro analyses indicated that adding LSG to protein isolates significantly reduced (p < 0.05) droplet size and enhanced encapsulation efficiency, antioxidant activity, and zeta potential. SPI-LSG nanoemulsions exhibited strong antioxidant activity over time. Encapsulation improved antibacterial efficacy against Staphylococcus aureus, with no significant effect on Escherichia coli. Microscopy showed good encapsulation and particle distribution. SPI-LSG was the most stable formulation and had better thermal stability. The incorporation level of DN-SPE into ricotta cheese (1% w/w) was selected based on preliminary formulation optimization experiments evaluating physicochemical stability, antioxidant performance, and sensory acceptability of the cheese matrix. Treatments mitigated alterations in physicochemical attributes, suppressed microbial growth, and preserved sensory quality. Rheological analysis showed shear-thinning, gel-like behavior in all samples, while DN-SPEs significantly increased apparent viscosity, loss modulus, and storage modulus (p < 0.05). Cheese containing DN-SPE-PL exhibited the greatest rheological parameters and enhanced hardness, gumminess, and chewiness. Overall, DN-SPE emulsions containing of PL or SL provided strong antioxidant and antimicrobial effects, improved the physicochemical and sensory quality of ricotta cheese, and demonstrated potential to extend its short refrigerated shelf life within the 14-day storage period.
