Infections and pathology of free-roaming backyard chickens on St. Kitts, West Indies.
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 6 papers.
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
Free-roaming chickens on Caribbean islands are important sentinels for local avian diseases and those introduced by birds migrating through the Americas. We studied 81 apparently healthy unvaccinated free-roaming chickens from 9 parishes on St. Kitts, an eastern Caribbean island. Using commercial ELISAs, no chickens had antibodies against avian influenza virus, West Nile virus, or Salmonella Enteritidis, although seropositivity was high to infectious bursal disease virus (86%), infectious bronchitis virus (84%), Mycoplasma (37%), and avian avulavirus 1 (Newcastle disease virus, 31%). Examination of small and large intestinal contents revealed cestodes in 79% and nematodes in 75% of the chickens. Although ectoparasites and endoparasites were common (74% and 79%, respectively), only a few chickens had lesions at postmortem examination, mainly intestinal serosal nodules (12%) and feather loss (6%). Histologic examination of 18 organs from each bird revealed lesions in high percentages of organs, mainly the liver (86%), lung (75%), spleen (60%), small intestine (56%), skin (42%), and kidney (40%). Lesions included degenerative, reactive, inflammatory, and neoplastic, and were not correlated with the serologic status of the chickens except in one case of infectious bursal disease. Microscopically, Paratanaisia bragai was seen in the kidneys of 3 chickens and intestinal coccidiasis in 1 chicken. Pulmonary silicate aggregates were common, were present in intestinal serosal nodules, and were suggestive of environmental exposure.
