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
Thermal aging is an effective strategy for improving the functional properties of fruit-based ingredients via physicochemical modifications. This research investigates the effect of thermal aging on the physicochemical, antioxidant, and Maillard conjugation properties of dried lychee pulp aged at 50, 60, 70, and 80 °C for 20 days under controlled relative humidity. Comprehensive analyses were performed, including total phenolic content (TPC), total flavonoid content (TFC), individual phenolic profiles, saccharide composition, free amino acid content, degree of glycation (DG), peptide molecular weight distribution, and antioxidant activity assessed by ABTS, DPPH, and FRAP assays. The results demonstrated that aging at moderate temperatures (60-70 °C) significantly enhanced TPC, TFC, and antioxidant activity, alongside an increased degree of glycation, peaking at approximately 47% at 70 °C. Principal component analysis (PCA) confirmed strong correlations between these compositional changes and antioxidant responses. In contrast, aging at 80 °C led to the degradation of thermolabile phenolics, sugars, and amino acids, resulting in reduced antioxidant activity compared with non-aged samples. Overall, the results highlight a temperature-dependent balance between constructive Maillard conjugation and thermal degradation, identifying 60-70 °C as an optimal aging range for improving the functional quality of dried lychee pulp. These findings provide mechanistic insight into thermal modulation of fruit bioactivity and support the potential application of controlled thermal aging in the development of value-added functional food ingredients.
