1 · What the graph read from 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.

2 · The registry

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

A sample of the diaphragm was collected from each of 100 wild boars legally hunted in the Val Grande National Park in north-western Italy and examined for the presence of Sarcocystis infection by histological and molecular methods. In histological sections, thick-walled sarcocysts consistent with those of Sarcocystis miescheriana were detected in 32 wild boars. Genomic DNA extracted from diaphragm samples was initially subjected to PCR amplification of the internal transcribed spacer 1 (ITS1) region, and 97 wild boars were found to harbour a Sarcocystis infection at this screening. Selected DNA samples were then subjected to PCR amplification and sequencing of the ITS1 region and the 18S and 28S ribosomal RNA (rRNA) genes of the nuclear ribosomal DNA unit, while all positive samples were subjected to PCR amplification of the mitochondrial cytochrome c oxidase subunit I (cox1) gene. S. miescheriana was identified in 97 wild boars (97%), while the zoonotic Sarcocystis suihominis was identified in one wild boar (1%), which also harboured S. miescheriana. Intra-specific sequence variation was found in all four DNA regions of S. miescheriana examined and in the 18S rRNA gene and ITS1 region of S. suihominis. The partial cox1 gene was amplified and sequenced from 72 isolates of S. miescheriana, yielding 43 haplotypes with pairwise sequence identities of 97.6-99.9%. These haplotypes were 79.1-79.8% identical with the cox1 sequence of S. suihominis. Phylogeny based on cox1 sequences placed S. miescheriana and S. suihominis as sister species within a clade comprising mainly Sarcocystis spp. of ruminants with felids as known or presumed definitive hosts. The same was true for the phylogeny based on 18S rRNA gene sequences.
