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

Feed additives have emerged as promising strategies to lower enteric methane (CH₄) emissions, with some achieving reductions of up to 30%. However, their widespread adoption is limited by inconsistent effects on productivity, regulatory barriers, and economic constraints. Combining feed additives with complementary modes of action might enhance mitigation outcomes, yet results vary depending on diet, adaptation period, additive interaction, and microbial dynamics in the rumen. This review synthesizes current knowledge on the efficacy, interaction effects, and implementation potential of feed additive combinations. It also examines economic incentives, such as carbon credit schemes, and recent policy developments that could accelerate adoption. While
