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
This study evaluated the effects of different stocking densities (high density-HD: 14 fish/tank; low density-LD: 7 fish/tank) on productive performance, lipidomic profile, and fatty acid composition in GIFT tilapia juveniles. Zootechnical parameters were analyzed, including relative growth, weight gain, feed conversion ratio, and fillet yield, along with lipidomic markers and fatty acids. Results showed that high density promoted better apparent feed conversion (p < 0.0001). However, low density led to higher apparent feed intake (p < 0.0001) and greater fillet yield (p = 0.0009), suggesting these fish utilized ingested nutrients to maximize fillet production. Lipidomic analysis revealed higher phospholipid turnover in low density (LD), with increased lysophosphatidylcholines (LPC) and lysophosphatidylethanolamines (LPE), while high density (HD) showed phosphatidylcholine (PC) accumulation, indicating less efficient lipid metabolism under stress. Additionally, LD had higher concentrations of polyunsaturated fatty acids (PUFAs) (p < 0.05), highlighting density's influence on nutritional quality. We conclude that low stocking density suggests an improvement in productive performance and fish quality, whereas high density induces metabolic responses indicative of chronic stress related to lipid metabolism.
