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

backgroundMutations in the Plasmodium falciparum k13 gene are associated with artemisinin (ART) resistance. However, it is unclear whether the F446I mutation, the most prevalent allele at the China-Myanmar border and north of Myanmar, is associated with ART resistance. Therefore, the aim of this study was to investigate the role of this mutation in ART resistance by generating transgenic parasites expressing the F446I mutant allele.

methodsThe transgenic parasites carrying the F446I or C580Y mutation in both 3D7 and FCC1/HN isolates were generated by single crossing-over recombination and verified using PCR and gene sequencing. The ring-stage survival assay of 0-3 h (RSA

resultsFour transgenic parasite lines named 3D7

conclusionsInsertion of the F446I mutation in k13 led to increased ring survival, suggesting that this mutation may be associated with ART resistance and could be used as a molecular marker for monitoring ART-resistant parasites. The results also highlights the importance of surveillance of F446I mutants for containing the resistant parasite.
