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

Extensive genome plasticity in Plasmodium involves frequent loss of dispensable functions under non-selective conditions, polymorphisms in subtelomeric repetitive regions, as well as rapid and apparently concerted variation in the intra-genic repetitive arrays that are typical of plasmodial antigen genes. As an example of the latter type of variation, the region of the merozoite surface antigen gene MSA-1 of Plasmodium falciparum, which encodes a tri-peptide repeat, is analysed in detail. The example illustrates how evasion of the immune defenses of the vertebrate host can be achieved through repeat homogenization mechanisms, acting at the DNA level, and leading to rapid fixation of variant epitopes. The remarkable ability of Plasmodia to utilize mechanisms which operate on its own nuclear DNA in the course of mitotic multiplication is discussed against the need of life cycle closure as a haploid unicellular. The possibility is suggested that active genomic diversification in a (clonal) multicellular population evolved as an adaptive tool.
