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 investigated the effects of different concentrate-to-roughage ratios on the rumen microbial community, functional potential, and fermentation characteristics in yak. Forty Qinghai Plateau-type yaks (8-9 months, 68.725 ± 18.973 kg) were randomly assigned to four dietary groups with concentrate-to-roughage ratios of 80:20 (C80), 65:35 (C65), 50:50 (C50), and 35:65 (C35). After a 15-day adaptation period, animals were fed for 105 days. Rumen contents were analyzed using metagenomic sequencing combined with fermentation parameter measurements. High-concentrate diets (C80 and C65) were associated with increased relative abundance of starch-degrading and propionate-producing bacteria, such as
