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

This study employed three distinct methods to prepare Peruvian squid liver protein hydrolysates (PSLPHs), characterized their structure, and evaluated their antioxidant activities. Furthermore, these hydrolysates were utilized as fertilizers to investigate their effects on the growth of tomato seedlings. The results indicated that PSLPHs prepared using the biological enzymatic hydrolysis combined with ultrasound-assisted autolysis (B&U) treatment demonstrated the highest content of aromatic amino acids (Tyr + Phe: 5.499 g/100 g). Additionally, the molecular weight was found to be 99.21 % below 3 kDa, exhibiting a total antioxidant activity of 52.73 %, with solubility exceeding 80 % at pH 5.5-6.5. Furthermore, when diluted 100-fold and applied as fertilizer for tomato seedlings, the PSLPHs promoted root system growth, and enhanced stem and blade growth. This research innovatively employed the B&U method to prepare PSLPHs and assessed their effects on the growth of tomato seedlings, providing a theoretical basis for the application of protein hydrolysate-based water-soluble fertilizers.
