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

The Piau is a naturalized Brazilian pig breed known for its disease resilience, low maintenance and nutritional requirements, and adaptability to diverse climatic conditions. Incorporating local breeds, such as Piau, into crossbreeding programs with commercial lineages may increase the productive performance of naturalized breeds while helping preserve their genetic diversity. This study evaluated the influence of genetic groups on the performance, carcass traits, and meat quality of barrows. Thirty-nine animals from four groups: purebred Piau (PP), Large White (LL), Piau × Large White (PL), and Duroc × Large White (DL) were analyzed in a completely randomized design. Performance, carcass yield, chemical composition, and meat quality (Longissimus dorsi and Biceps femoris) were assessed. Results showed that PP had the lowest growth rates, while DL exhibited the highest productive efficiency. The PL crossbreed showed significantly higher hot carcass weight compared to PP, reaching levels near those of commercial groups while retaining the high backfat thickness characteristic of the Piau breed. Regarding meat quality, PP and PL showed superior water-holding capacity and lower drip loss compared to commercial lines. Although shear force was similar for the loin across groups, DL had the most tender ham (Biceps femoris), while PL showed lower tenderness for this cut. In conclusion, crossbreeding Piau with Large White (PL) increases performance and carcass weight in comparison to purebred Piau without compromising the distinctive moisture retention and fat attributes of the local breed. The highest productive performance was observed for the Duroc × Large White cross.
