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
In this study, astaxanthin extract was obtained from deep-water pink shrimp (Parapenaeus longirostris) shell wastes by ultrasound-assisted extraction method using six different organic solvents, characterized and compared with commercial astaxanthin standard. Astaxanthin extractions were performed under different time conditions (2 and 4 h) using selected apolar/polar solvents (petroleum ether, hexane, isopropanol, ethanol, methanol, acetone). All extracts were quantitatively tested by high-performance liquid chromatography. The results show that solvents with higher polarity are more suitable for astaxanthin extraction, and the effect of time on extraction yield varies with the type of solvent. The highest astaxanthin concentration was obtained after 2 h of extraction using methanol (310 ±2.00 µg/g) and the lowest value after 4 h of extraction using petroleum ether (104 ± 30.00 µg/g) (p < 0.05).The UV-Vis spectra of astaxanthin extract showed maximum absorbance in the visible region in the range of 480-520 nm, which is the characteristic absorbance of astaxanthin. Fourier transform infrared spectrometry (FTIR) spectrometry was used to confirm the fingerprint region of astaxanthin extract with C = O stretching vibration, methyl group (aliphatic) (-CH), ketone group (-C = O) (6-membered ring), alkenes (C-C, C = C) and C-CH
