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

aimsResistance to the artemisinins and the artemisinin-based combination therapy (ACT) partner drugs has developed in Southeast Asia, and artemisinin resistance has also emerged in eastern Africa. Triple ACTs (triple artemisinin-based combination therapies, TACT), consisting of two partner drugs with different mechanisms of action and similar pharmacokinetic profiles, combined with an artemisinin derivative can help to delay or prevent artemisinin resistance and prolong the useful lifetime of the partner drugs. This study aims to characterize the pharmacokinetic properties of a recommended TACT, artemether-lumefantrine plus amodiaquine, using data from two large clinical trials.

methodsWe analysed data from two randomized, controlled intervention trials conducted between 2015 and 2020 in one African country and two Southeast Asian countries, in which artemether-lumefantrine was administered alone (n = 443) or together with amodiaquine (n = 442) to patients with uncomplicated P. falciparum malaria. Both studies included a sub-cohort with dense pharmacokinetic sampling, combined with sparse data in the other patients. Concentration-time data of artemether, dihydroartemisinin, lumefantrine, desbutyllumefantrine, amodiaquine and desethylamodiaquine were analysed using nonlinear mixed-effects modelling.

resultsPharmacokinetic models were developed for all drugs and demonstrated good predictive performance and goodness-of-fit diagnostics. Coadministered amodiaquine was not a significant covariate on pharmacokinetic properties of artemether-lumefantrine. Model-predicted C

conclusionsThe DDI effect of amodiaquine on the pharmacokinetics of artemether-lumefantrine is expected to be minimal, the based on the current analysis. However, further large-scale clinical trials are needed to confirm this finding.
