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

The metabolic impact of the breeding season on beef bulls has not been extensively studied. The change in plane of nutrition and intensive activity demands induce body weight loss and metabolic changes that may influence fertility and long-term management. The use of metabolomics to characterize the metabolic changes or adaptations during the breeding season will aid in developing hypotheses for future research in beef bulls. The objective of this study was to identify metabolites in both serum and seminal fluid (circulating vs. excretory) that were affected temporally throughout a 65-d breeding season and by bull workload (bull: cow). Over a two-year period, purebred Angus bulls (year 1:
