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: Desert truffles ( Methods: Seven preservation techniques (sun drying, oven drying, deep freezing, lyophilization, chips processing, marination, and olive-oil preservation) were assessed. Nutritional composition, mineral content, vitamins, carotenoids, phenolic compounds, and antioxidant activity were determined using standard analytical methods. Data were analyzed by two-way ANOVA to evaluate the effects of preservation method, species, and their interaction. Results: Preservation method was the main source of variation, explaining up to 99.06% of protein, 95.65% of carbohydrate, 94.88% of antioxidant activity, 88.19% of potassium, and 87.07% of total phenolic variability (all P < 0.0001), whereas species effects were comparatively minor. Oven drying and lyophilization best preserved protein content (≈27-28%) and antioxidant activity (87-89% radical scavenging activity). Lyophilization and marination retained the highest mineral concentrations, while lyophilization also preserved the greatest riboflavin (2.69-3.94 ppm) and lycopene (0.15-0.16 ppm) contents. Oven drying produced the highest phenolic acid levels, whereas chips processing consistently reduced proteins, minerals, vitamins, and bioactive compounds. Discussion: Preservation method is the principal determinant of the nutritional and nutraceutical quality of desert truffles. Oven drying and lyophilization were the most effective strategies for maintaining health-promoting compounds, supporting their application as optimal post-harvest technologies to maximize the functional food value and commercial potential of
