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 North American swine industry is shifting towards raising pigs to heavier weights, partly due to the potential for higher profitability for pork processors. However, producers may incur losses due to feed and transportation costs associated with heavy-weight pigs. In some cases, these animals can fall outside grid-based grading specifications, resulting in discounts for carcasses that are too heavy or too lean/too fat. Furthermore, increasing weight raises concerns regarding nutritional requirements, feed efficiency, environmental sustainability, welfare issues, carcass composition, chilling rate, meat quality, and implications for genomic selection. Variation exists for growth performance traits and carcass composition across genotypes. In this review, we summarise the biological, physiological, and genetic mechanisms underlying the effect of increasing weight in contemporary pig production. A comprehensive understanding of animal performance, animal welfare, carcass traits and genetic regulations in heavy-weight pigs will be significant for refining breeding goals, precision feeding strategies and handling practices.
