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

Over the past decade, attempts to explain the unusual size and prevalence of low-complexity regions (LCRs) in the proteins of the human malaria parasite Plasmodium falciparum have used both neutral and adaptive models. This past research has offered conflicting explanations for LCR characteristics and their role in, and influence on, the evolution of genome structure. Here we show that P. falciparum LCRs (PfLCRs) are not a single phenomenon, but rather consist of at least three distinct types of sequence, and this heterogeneity is the source of the conflict in the literature. Using molecular and population genetics, we show that these families of PfLCRs are evolving by different mechanisms. One of these families, named here the HighGC family, is of particular interest because these LCRs act as recombination hotspots, both in genes under positive selection for high levels of diversity which can be created by recombination (antigens) and those likely to be evolving neutrally or under negative selection (metabolic enzymes). We discuss how the discovery of these distinct species of PfLCRs helps to resolve previous contradictory studies on LCRs in malaria and contributes to our understanding of the evolution of the of the parasite's unusual genome.
