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

In this study, corn protein hydrolysates (CPT) were prepared via enzymatic hydrolysis using Alcalase and Protamex, and then fractionated by ultrafiltration into three molecular weight components: >5 kDa (CPT1), 3-5 kDa (CPT2), and <3 kDa (CPT3). The physicochemical, functional and in vitro antioxidant properties of each component were systematically compared. Subsequently, glutamine peptides were isolated and identified from CPT3 using LC-MS/MS technology, and the structural characteristics of the identified peptides were further analyzed. The results showed that the ultrafiltration fractionation effectively enriched peptides with lower molecular weights from the enzymatically hydrolyzed products, which may potentially enhance their bioavailability. In addition, CPT3 exhibited superior foaming ability, emulsifying ability, dispersibility, and zeta potential, along with lower particle size and viscosity. Moreover, CPT3 exhibited strong antioxidant activity, with IC
