Mycoplasma conjunctivae in domestic small ruminants from high mountain habitats in Northern Spain.
Article in BMC veterinary research, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
backgroundInfectious keratoconjunctivitis (IKC) is a clinical condition affecting eyes of domestic and wild Caprinae worldwide, and Mycoplasma conjunctivae is considered the primary causative agent of IKC in sheep, goats and wild Caprinae. Domestic ruminants from high mountain habitats share grazing areas with wild mountain ungulates, such as chamois (Rupicapra spp.), Alpine ibex (Capra ibex) and European mouflon (Ovis aries musimon), and domestic sheep seem to act as M. conjunctivae reservoir. In this study, the presence of M. conjunctivae in domestic sheep and goats from the two main mountain ranges of Northern Spain, the Pyrenees and the Cantabrian Mountains, has been investigated.
resultsEye swabs were obtained from 439 domestic small ruminants selected from flocks that seasonally graze in alpine meadows during three consecutive years (2011-2012-2013). Seventy-nine out of the 378 domestic sheep (20.9%) tested positive to a M. conjunctivae specific real time-PCR (rt-PCR) in at least one eye, whereas all the 61 sampled domestic goats were negative. Statistically significant higher prevalence and higher proportion of infected flocks (P < 0.001) was observed in the Pyrenees (25.7%; 12 flocks out of 13), where M. conjunctivae is widespread and probably endemic in domestic sheep, than in the Cantabrian Mountains (7.8%; one flock out of six). Twenty-five sheep (three from the Pyrenees and 22 from the Cantabrian Mountains) which showed clinical signs consistent with infectious keratoconjunctivitis (IKC) were negative by rt-PCR. In contrast, 62 out of the 71 (87.3%) M. conjunctivae-positive sheep from the Pyrenees and the eight positive sheep from the Cantabrian Mountains were asymptomatic.
conclusionsThis study provides rt-PCR-based evidences of M. conjunctivae maintenance in domestic sheep, as well as a relationship between prevalence in domestic sheep and previously reported M. conjunctivae and IKC in wild ruminants. Domestic goats do not seem to play an important role in the epidemiology of M. conjunctivae in alpine habitats from Northern Spain.
