Detection, Identification, and Characterization of Eimeria spp. from Commercial Chicken Farms in Different Parts of Iran by Morphometrical and Molecular Techniques.
Article in Acta parasitologica, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
purposeCoccidiosis of domestic chicken is an important disease caused by any of seven species of Eimeria which, by developing within the epithelial cells of the intestine, cause lesions therein. We carried out a study on poultry farms located in various regions of Iran to determine the incidence and spread of Eimeria species by employing a single PCR test.
methodsA total of 64 fully confirmed clinically intestinal tracts were collected from different parts of Iran. From these 64 intestinal tracts, 82 samples were prepared from the different sites involved in the digestive tract. In morphological assessment, 23 samples could not be isolated and its information was not evaluated.
resultsUsing morphological methods, the following seven species of Eimeria were identified: E. acervulina (15/59; 25.42%), E. tenella (30/59; 50.84%), E. maxima (12/59; 20.33%), E. praecox (1/59; 1.69%), E. necatrix (2/59; 3.38%), E. mitis (5/59; 8.47%), and E. mivati (2/59; 3.38%). Mixed infections were found in eight (13.55%) samples. In molecular assessment, 31 samples could not be isolated and its information was not evaluated. Totally, the following five species were identified using molecular methods: E. acervulina (35/51; 68.62%), E. tenella (33/51; 64.70%), E. maxima (6/51; 11.76%), E. brunetti (5/51; 9.80%), and E. necatrix (2/51; 3.92%). Mixed infections were found in 23 (45.09%) samples.
conclusionsThe present study is an update on the situation of poultry coccidiosis in Iran and provides the first data on the molecular detection, identification, and characterization of Eimeria spp. in the poultry population of this country and confirmed the presence of different species of this parasite in this area. According to the results, E. acervulina and E. tenella, as the main disease-causing species, should be considered in control programs such as treatment and vaccination strategies.
