Serological evidence of bovine viral diarrhea virus and peste des petits ruminants virus infection in alpacas (Vicugna pacos) in Shanxi Province, northern China.

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
Bovine viral diarrhea virus (BVDV) and peste des petits ruminants virus (PPRV) are two important pathogens associated with a variety of disease syndromes that result in substantial financial losses in animal husbandry. This study was performed to assess the seroprevalence of antibodies to BVDV and PPRV among alpacas raised in Shanxi Province of northern China. Serum samples were obtained from 246 alpacas in Taiyuan (n=182), Xinzhou (n=31), and Jinzhong cities (n=33) of Shanxi Province, and serological testing was carried out using the competitive enzyme-linked immunosorbent assay. Overall seroprevalence to BVDV was 3.25% (95% CI 1.03-5.47), and seropositive alpacas were found only in Taiyuan City. The overall PPRV seroprevalence in alpacas was 28.86% (95% CI 23.20-34.52). While no PPRV-seropositive alpacas were found in Xinzhou City, the seroprevalence of PPRV was 90.91% (95% CI 81.10-100.72) in Jinzhong City and 22.53% (95% CI 16.46-28.60) in Taiyuan City, respectively, which showed a statistically significant difference. To our knowledge, the present work is the first report on seroprevalence of BVDV and PPRV in alpacas in China, which provides baseline information for the control of infection.
