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 potential changes in limiting amino acid (AA) requirements for lactating sows fed low-protein (LP) diets and the underlying physiological mechanisms remain unclear. This study evaluated the productive and physiological responses of lactating sows to LP diets, focusing on the optimal standardized ileal digestible lysine (SID Lys) supply. A total of 84 Landrace × Large White sows with similar parity (4.06 ± 0.16), expected farrowing dates and body weight (BW; 260.65 ± 1.25 kg) were randomly assigned to 6 groups with 14 replicates in each group and 1 sow per replicate. The control diet (CON) contained 18% crude protein (CP) and 0.78% SID Lys. Five LP diets contained 15% CP and similar net energy (NE) levels, with SID Lys levels of 0.66%, 0.72%, 0.78%, 0.84%, and 0.90%, respectively, achieved by adjusting the corn-to-soybean meal ratio and crystalline amino acids (CAAs) supplementation. The trial lasted for 28 d (from d 107 of gestation to d 21 postpartum). Compared with CON, 0.78% SID Lys-LP diet increased milk immunoglobulin M content (
