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

The major aim of the present study was to determine by molecular methods whether the wide and narrow types of macroscopic sarcocysts in Spanish sheep belonged to different species, that is, Sarcocystis gigantea and Sarcocystis medusiformis, respectively. Additionally, we wanted to identify and characterize molecularly the species forming microscopic sarcocysts and determine the phylogenetic placement of all species found. Portions of the oesophagus, diaphragm and hind legs containing macroscopic sarcocysts were collected from slaughtered culled ewes at an abattoir in the Province of Madrid, Central Spain, but both macroscopic and microscopic sarcocysts were isolated for molecular examination. Genomic DNA from 63 sarcocysts (21 macroscopic, 42 microscopic) were examined at the cytochrome c oxidase subunit I gene (cox1), while selected isolates of each species found were further examined at the 18S and 28S ribosomal RNA (rRNA) genes. The 63 sarcocysts comprised five cox1 sequence types, each corresponding to a particular sarcocyst type, and thus represented five Sarcocystis spp. The slender fusiform and thick macrocysts belonged to S. medusiformis and S. gigantea, respectively. The microscopic sarcocysts belonged to Sarcocystis arieticanis, Sarcocystis tenella and a Sarcocystis mihoensis-like species with slanting thorn-like cyst wall protrusions, which was characterised molecularly for the first time. Based on its phylogenetic position, the S. mihoensis-like species probably uses corvids as definitive hosts.
