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

Resistance to piperaquine has been associated with the amplification of the plasmepsin II gene in Cambodia. None of the 175 African isolates that we analyzed had plasmepsin II gene amplification (piperaquine 50% inhibitory concentration ranged from 0.94 to 137.5 nM), suggesting there is a low prevalence of piperaquine reduced susceptibility in Africa. Additionally, the few isolates with reduced susceptibility to piperaquine did not harbor amplification of the plasmepsin II gene.
