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

Continued genetics and management improvement necessitates the verification of nutrient requirements for prolific and high-producing modern sow. Therefore, the objective of this study was to determine the standardized ileal digestible (SID) linoleic acid (LA) requirement of lactating sows using dose-response estimation methods. A total of 100 healthy Yorkshire × Landrace sows (parity two to four; initial body weight 245.0 ± 15.8 kg) were randomly assigned to five treatment groups with 20 replicates per group. The five diets contained 1.47%, 1.91%, 2.32%, 2.74%, or 3.15% SID LA. The experimental period lasted 28 d from d 107 of gestation until weaning. Reproductive performance of sows were not affected by dietary SID LA levels (
