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

Cryptococcus neoformans is an encapsulated pathogenic yeast producing meningoencephalitis. Two primary strains in genetic studies, serotype A H99 and serotype D JEC21, possess dramatic differences in virulence. Since it has been shown that mitochondrial gene expression is prominent at the site of the infection and there are significant differences between mitochondrial gene structure and regulation between the serotype A and D strains, this study used AD hybrids to move serotype A and D mitochondria under different genomic influences. When the serotype D MATa strain is involved in the mating crosses, there is uniparental transmission of mitochondrial DNA, but with the serotype A MATa strain, mitochondrial DNA can be inherited from either parent and recombination in the mitochondrial genome may also occur. In virulence studies between serotype A and D strains, it was found that the primary genetic control of the virulence composite for growth in the central nervous system is encoded in the nuclear DNA and not through mitochondrial DNA.
