Sero-epidemiology of porcine parvovirus, circovirus, and classical swine fever virus infections in India.
Article in Tropical animal health and production, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Reproductive problems in swine caused by porcine viruses pose a serious threat to the pig industry in developing countries like India. For evaluating the true extent of porcine infections, a total of 1308 representative sera samples were collected from 92 different pig farms covering 8 North-Eastern states and Punjab state of Northern India during a period of 2 years (2011-2013). Sera samples were tested for the presence of antibodies against porcine parvovirus (PPV), porcine circovirus-2 (PCV-2), and classical swine fever virus (CSFV) using commercial enzyme-linked immunosorbent assay (ELISA) kits. In the North-Eastern states, the seroprevalence of CSFV in non-vaccinated animals was 6.30% and that of PCV2 and PPV was 6.28% and 1.24%, respectively. In Punjab, the seroprevalence of CSFV in non-vaccinated animals was 44.44% and seroprevalence of PCV-2 and PPV was 34.07% and 39.10%, respectively. Detection of antibodies against more than one virus revealed that 4.66% animals had co-infection with PCV-2 and PPV, 1.75% with CSF and PPV, 1.98% with CSF and PCV-2, and 1.75% with all the three viruses. The receiver operator characteristics (ROC) curve analysis depicted that piglet mortality, parvovirus, and CSFV were the most important parameters with an AUC value of 0.997, 0.897, and 0.973, respectively. Incidence of single or co-infection with different viruses showed that the occurrence of single infection was significantly more prevalent than co-infection. This study provides useful information to set up future epidemiologic, flock management, and public animal health policies for the prevention and control of PCV-2, PPV, and CSF in India.
