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

Early embryonic implantation quality is a key determinant of litter performance in sows. Selenium plays a vital role in maintaining optimal female reproductive performance. This study aims to assess the impact of selenium yeast supplementation during early pregnancy on embryo implantation efficiency and litter size in sows. This trial involved multiparous Landrace × Yorkshire (L × Y) crossbred sows. The control group ( IMPORTANCE: This study demonstrated that selenium yeast supplementation during early pregnancy plays a critical role in reproductive performance. It improves embryo implantation quality and increases litter size. Systematic evaluation of selenium yeast supplementation revealed that it significantly enhances maternal antioxidant capacity and progesterone concentrations. Furthermore, it promotes the enrichment of beneficial
