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

Ambient temperature is an important factor affecting metabolic processes in animals, and its effect on energy metabolism is becoming more evident. Yet, integrative analysis of energy metabolism in finishing pigs at different combinations of ambient temperature, energy density and energy sources, still remain underexplored. In order to determine the special characteristics of energy metabolism of finishing pigs in low-temperature environment, the effects of different combinations of ambient temperature, energy density, and energy source on underlying mechanisms were elucidated by assessing energy metabolism using integrative indirect calorimetry and non-targeted plasma metabolomics analyses. Thirty-two finishing pigs (Duroc × Large White × Landrace) with similar body weight of 85.44 ± 2.04 kg were allotted in a 2 × 2 × 2 factorial arrangement (8 treatment groups, 4 replicates per group, 1 pig per replicate), which included two ambient temperatures (low temperature [10 °C] and normal temperature [20 °C]), two energy densities (normal energy density [NE, 14.02 MJ/kg] and high energe density [HE, 15.14 MJ/kg]), and two energy sources (low-oil source and high-oil source). The experiment period lasted 11 days. Increasing the energy density of the diet by adding oil changed the energy source in a low-temperature environment, improved crude fat digestibility (
