Evaluation of serologic testing of rams in the management of Brucella ovis in a domestic sheep flock.
Article in Journal of veterinary diagnostic investigation : official publication of the American Association of Veterinary Laboratory Diagnosticians, Inc, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled 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.
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
Brucella ovis is a bacterial pathogen present in most major sheep-producing regions of the world. The pathogen is associated with ram infertility, decreased ewe conception rates, and premature lambs. Twenty ELISA seropositive or indeterminate rams were culled from a B. ovis-positive flock, and donated to the Wyoming State Veterinary Laboratory for evaluation of infection. Tissues from each ram were collected at autopsy for additional testing, including bacterial culture, PCR, and histopathology. Of 17 seropositive rams, 11 rams were also positive by culture and PCR, and had evidence of mild histologic lesions; 1 seropositive ram was positive by culture with mild histologic lesions, but negative by PCR. Five seropositive rams were negative by culture and PCR and had no histologic lesions. Three indeterminate rams were negative by culture and by PCR and had no histologic lesions. The tissues in which B. ovis was most often detected included the epididymis, vesicular gland, and ampulla. Although this was a small study, the observation that 5 of 17 (29%) rams that were initially seropositive had no evidence of infection is interesting. A convalescent test for valuable seropositive animals prior to culling may be useful, and reproductive tissues may be evaluated postmortem if confirmatory testing is desired.
