Influence of High-Genetic-Potential Lineages and Sex on Carcass Traits and Pork Quality.
Article in Animals : an open access journal from MDPI, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 sex and genetics on carcass traits and pork quality in 180 carcasses from castrated males and females of three commercial lines: A (Pietrain × Duroc × Large White × Landrace), B (Line A × Pietrain) and C (Line A × Hampshire). Males showed greater backfat (14.05 vs. 13.38%) and lower lean meat (58.65 vs. 59.08%) than females. Line C exhibited the highest marbling score (2.82) and hot and cold carcass weights (90.04 and 88.05 kg), while Line B achieved the highest ham yield (32.5%). Castrated males had higher marbling (2.74 vs. 2.48) but lower shear force (3.68 vs. 3.90 kgf) than females. Line C showed the highest marbling (2.82) and shear force (4.04 kgf). Males of Line C had longer sarcomeres than females of the same line and males from Line B. Males exhibited higher protein (24.73 vs. 23.91%) but lower mineral content (1.55 vs. 1.85%) than females. Line A had the highest mineral content (1.90%). Collagen content was highest in males from Lines A and B (insoluble: 0.35-0.38%; soluble: 0.09%; total: 0.44-0.47%), and lower in Line C (insoluble: 0.18%; soluble: 0.04%; total: 0.21%). These results indicate that sex and new genetic lines influence carcass composition and instrumental meat quality traits.
