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

This study aimed to investigate the effects of supplementing rumen-protected glycine and methionine to low-protein diets on the growth and development of Yudong black goats. Sixty 4-month-old Yudong black goats with comparable body weights (21.0 ± 0.74 kg) were randomly assigned to four groups: the control (CON), rumen-protected glycine (GLY), rumen-protected methionine (MET), and mixed-amino-acid (MAG) groups. The CON group was fed a basal diet containing 13.4% crude protein, whereas the GLY, MET and MAG groups received diets with 11.0% crude protein supplemented with 4 g/kg rumen-protected glycine, 4 g/kg rumen-protected methionine, and 2 g/kg rumen-protected glycine + 2 g/kg rumen-protected methionine, respectively. The experimental period lasted 60 days. Compared with the CON group, supplementation with glycine or methionine alone did not affect the growth performance of goats (
