1 · What the graph read from it

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.

2 · The registry

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

Alzheimer's disease (AD) involves oxidative stress in brain tissue, creating a need for stable neuroprotective agents. Anthocyanins are potent antioxidants, but they are highly susceptible to degradation. This study evaluated anthocyanins from purple corn (PCA) and camu-camu (CCA) and the copigmentation effects of the phenolic acids cinnamic (C), ferulic acid (F), resveratrol (R) and polyaspartic acid (P) on the stability and neuroprotective capacity of these anthocyanins. HPLC-MS analysis identified twelve anthocyanins in PCA, including a new one (petunidin sophoroside). Copigmentation was assessed via UV-Vis spectroscopy, FTIR, TG, and stability tests at pH 7.4. The TBARS assay evaluated protection against oxidative stress in brain tissue. Copigment R provided the strongest hyperchromic effect for PCA, while P was most effective for CCA. TG analysis showed that copigmentation with R significantly improved the thermal and pH stability of both anthocyanin sources. All single copigmented samples showed improved stability of anthocyanins in physiological conditions. Furthermore, R-copigmented anthocyanins exhibited the most potent neuroprotective effects, significantly inhibiting lipid peroxidation. Thus, copigmentation, particularly with R, is a highly effective strategy for stabilizing anthocyanins and enhancing their potential as neuroprotective agents against oxidative stress.
