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

Plasmodium vivax msp1p, a paralog of the candidate vaccine antigen P. vivax merozoite surface protein 1, possesses a signal peptide at its N-terminus and two epidermal growth factor-like domains at its C-terminus with a glycosylphosphatidylinositol attachment site. The msp1p gene locus may have originated by a duplication of the msp1 gene locus in a common ancestor of the analyzed Plasmodium species and lost from P. yoelii, P. berghei, and P. falciparum during their evolutionary history. Full-length sequences of the msp1p gene were generally highly conserved; they had a few amino acid substitutions, one highly polymorphic E/Q-rich region, and a single-to-triple hepta-peptide repeat motif. Twenty-one distinguishable allelic types (A1-A21) of the E/Q-rich region were identified from worldwide isolates. Among them, four types were detected in isolates from South Korea. The length polymorphism of the E/Q-rich region might be useful as a genetic marker for population structure studies in malaria-endemic areas.
