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

Statistical analysis of the relationship between pre-parturition backfat thickness and reproductive performance using a large dataset of 693 sows (gilts) revealed that both high and low backfat as detrimental to the optimal reproductive performance of sows. Further analysis indicated that the health and reproductive performance of sows are compromised by problems such as excess backfat deposition due to ad libitum feeding and reduced satiety due to restricted feeding. Despite the consensus that dietary fiber (DF) supplementation of sows during gestation improves their health and performance, there is currently disagreement about the appropriate type of DF to select. In this review, the definition of DF is revised by integrating its physicochemical properties and fermentability, and the definition of functional dietary fiber (FDF) applicable to breeding pig breeding is proposed. Additionally, the mechanisms by which FDF regulates sow constipation, satiety, lactational feed intake and reproductive performance are elaborated in detail. This review provides a theoretical basis for selecting reasonable fiber sources for sow production.
