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

Toxoplasma gondii tachyzoites and bradyzoites are studied extensively in the laboratory due to the ease with which they can be cultured. In contrast, oocysts and the sporozoites within them are more difficult to work with, in that cat infections are required for their generation and isolating sporozoites requires a laborious excystation procedure. More over some parasite species such as Hammondia hammondi are obligately heteroxenous and require passage through a cat for completion of the life cycle. There is no debate that there is great value in studying this important life cycle stage, and we present here a detailed description of the current protocols used in our laboratories to generate and isolate T. gondii and H. hammondi oocysts, and to excyst and purify the sporozoites within them for use in downstream experimental applications.
