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

Goatskin by-products are generated in large quantities annually from slaughterhouses, resulting in resource waste and environmental pollution. Despite the considerable application potential of collagen, the primary component of goatskin, its extraction, and its utilization remain limited, particularly in gel-based food products. This study aims to extract goatskin collagen using a hydrothermal technique and elucidate how the hydrothermal intensity (60°C-100°C, 3-9 h) affects gel properties through structural changes. The results showed that gel properties were markedly affected by the extraction intensity. Mild conditions (3 h-60°C) produced collagen with the greatest gel strength (1569 g), along with the highest melting (35.1°C) and gelling (34.2°C) temperatures and the brightest color. In contrast, harsher conditions significantly reduced gel strength, lowered transition temperatures, and darkened gel appearance. Rheological analysis also confirmed weakened viscoelasticity and earlier structural breakdown under intensive treatments. Structural analysis further demonstrated that increasing hydrothermal intensity caused pronounced collagen degradation, increased small fragments, disordering of secondary structures with reduced
