Molecular detection of Cryptosporidium spp. in semi-intensive pig production systems in the state of São Paulo, Brazil.

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
Considering the importance of pigs acting as a source of infection for zoonotic protozoan species, this study aimed to investigate the prevalence and perform the molecular characterization of Cryptosporidium spp. in pigs raised in semi-intensive production systems in the municipality of Araçatuba, state of São Paulo, Brazil. Two hundred fecal samples from pigs raised in four farms were collected between March and August 2018. Detection and speciation of Cryptosporidium spp. were performed by nested PCR of small subunit ribosomal RNA (18 S rRNA) gene followed by Sanger sequencing. The chi-square statistical test was performed to verify the association between positivity and negativity for Cryptosporidium spp. with the age of the pigs. Cryptosporidium spp. were identified in 34/200 (17%) samples. Sequencing of amplified fragments identified Cryptosporidium scrofarum in ten samples. No statistical significance was observed between the positivity and age of the animals. The presence of C. scrofarum, a potentially zoonotic protozoan, was confirmed in domestic pigs for the first time in the state of São Paulo, Brazil.
