Does the methanogenesis inhibitor 3-nitrooxypropanol affect milk yield in dairy cattle?
Review in Veterinary evidence. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
PICO question: In dairy cattle, does the methanogenesis inhibitor 3-nitrooxypropanol affect milk yield, compared to cows that receive no intervention to reduce enteric methane emissions? Clinical bottom line: Category of research: Treatment. Number and type of study designs reviewed: A total of 15 controlled trials were critically reviewed, of which 11 were randomised. Strength of evidence: Moderate. Outcomes reported: Eleven studies reported no effect of 3-nitrooxypropanol (3-NOP) on milk yield at doses ranging from 40 to 135 mg of 3-nitrooxypropanol/kg of feed dry matter (DM). Two studies reported trends for decreased milk yield at doses greater or equal to 80 mg of 3-NOP/kg of feed DM, while a further two studies reported statistically significant declines in milk yield at doses of 80 mg of 3-NOP/kg of feed DM. Conclusion: The reviewed studies provide a moderate strength of evidence to support that the administration of the methanogenesis inhibitor 3-NOP at concentrations less than 80 mg/kg of feed DM does not significantly affect milk yield in dairy cattle. Some studies suggest that 3-NOP may adversely affect milk yield at higher doses but the results are inconsistent.
