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
Mackerel is widely favored by consumers as a high-yield, delicious marine fish. However, by-products generated during its processing, such as fish skins, are often underutilized, resulting in significant resource waste. This study aimed to extract high-activity mackerel protein peptides (HA-MPPs) from mackerel skins through targeted enzymatic hydrolysis (using a composite protease). The peptides were purified using ultrafiltration and HPLC, and their biological activity was evaluated through infrared imaging and antioxidant assays. Mass spectrometry identified the main peptide fragments (P1, P2, and P3). The optimal conditions for enzymatic hydrolysis were 0.22% enzyme concentration, a 2.03 h hydrolysis time, 55.05 °C, and a 1:3 solid-to-liquid ratio, yielding 59.66%. Infrared imaging showed that HA-MPPs exhibited significant biological repair activities, penetrating the hair cuticle to restore keratin and enhance hair strength. Additionally, antioxidant assays confirmed their abilities to reduce oxidative damage. This study presents a novel method for the targeted enzymatic extraction of HA-MPPs from mackerel by-products and the high-value utilization of their biological activity. It also demonstrates the potential of these peptides in hair repair, providing a theoretical foundation for the future development of hair care products with reparative functions.
