Impact of Drying and Storage Conditions on the Bioactive and Nutritional Properties of Malolactic Wine Lees.

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
Wine lees, a winemaking by-product, have high potential for reuse due to their significant phenolic content and antioxidant capacity. To preserve their composition and enhance their feasibility for incorporation into food products, this study evaluated the effects of oven drying (40 °C) and freeze-drying on the physicochemical and nutritional characteristics of malolactic lees, as well as the impact of the storage time. Samples were analyzed at 0, 45, and 90 days of storage at 25 °C under light exposure conditions. Total phenolic content was determined by Folin-Ciocalteu, antioxidant activity by DPPH and FRAP assays, and phenolic groups by HPLC-DAD-FD. Both methods preserved a high protein content (~20%), with 44.66% essential amino acids and an essential amino acid index of 1.55, indicating high-quality proteins. The freeze-dried lees showed a higher phenolic content (77.92 mg GAE/g), whereas the oven-dried lees exhibited greater antioxidant activity, likely due to the formation or release of bound phenolic compounds induced by thermal processing. Among the phenolic groups, tannins were the most favored in terms of preservation. Storage time significantly influenced the parameters evaluated, indicating the impact of drying on stability. While freeze-drying better preserved phenolic compounds, oven drying was considered the most suitable option for large-scale application.
