Molecular characterization of rotavirus isolated from alpaca (Vicugna pacos) crias with diarrhea in the Andean Region of Cusco, Peru.
Article in Veterinary microbiology, 2015. 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
Alpacas (Vicugna pacos), a species of South American camelids (SAC), suffer high morbidity and mortality from infectious diseases. Diarrhea is one of the leading causes of alpaca cria mortality in Peru and elsewhere. In order to develop appropriate control and/or treatment, it is necessary to identify infectious pathogens that cause diarrhea in crias. Rotavirus was isolated in cell culture from feces collected from crias with acute diarrhea that tested positive to rotaviral antigen by rapid immunochromatographic methods in an earlier study. The isolates were identified as rotaviruses by RT-PCR run with specific primers for human rotavirus VP7 coding sequences using total RNA extracted from cells displaying cytopathic effects as template. These alpaca isolates were further identified as group A rotaviruses by means of a VP6-specific PCR and were designated as ALRVA-K'ayra/Perú/3368-10 and ALRVA-K'ayra/Perú/3386-10. Molecular G and P typing, placed the former as G3/P11 and the latter as G3/P?. Sequence analysis of two genome segments (coding for VP4 and VP7) from the alpaca isolates revealed partial homologies to swine and human rotaviruses, respectively. These results demonstrate that rotaviruses are associated with a proportion of cases of diarrhea in crias, although prevalence and impact remain to be determined. The isolation of rotaviruses from alpaca crias with diarrhea will contribute positively to further understand the pathogen and its role in the diarrhea complex.
