Monitoring the Efficacy and Safety of Artemisinin-Based Combination Therapies: A Review and Network Meta-analysis of Antimalarial Therapeutic Efficacy Trials in Cameroon.
Review in Drugs in R&D, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 papers, 3 of them syntheses that pooled 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.
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
introductionArtemisinin-based combination therapies (ACTs) are the first-line antimalarial drugs used to treat uncomplicated Plasmodium falciparum alaria in many endemic countries worldwide. The present work reviewed the therapeutic efficacy of ACT in Cameroon more than 10 years after the initial change in national drug policy in 2004.
methodsA PubMed literature search was performed to analyse clinical trials conducted in Cameroon from 2001 to May 2017. Clinical studies that evaluated ACT for the treatment of uncomplicated falciparum malaria in children or adults, and reported efficacy and/or safety, were included. In addition, a small network meta-analysis (NMA) with a frequentist approach was performed.
resultsSix papers were selected from 48 articles screened and were full-text reviewed. The efficacy of both artemether-lumefantrine (AL) and artesunate-amodiaquine (ASAQ) ranged from moderate to high, with polymerase chain reaction-corrected cure rates ranging from 96.7 to 100% and 88.2 to 100%, respectively, in per-protocol analysis, and 86.2 to 96.7% and 74.0 to 90.6%, respectively, in intention-to-treat analysis. The malaria evidence network suggested that AL and ASAQ efficacies were comparable. The highest day 3 parasite positivity rate was 8.2% for ASAQ and 4% for AL. A novel ACT, artesunate-atovaquoneproguanil (ASATPG) was tested once and showed a cure rate of 100%. Based on an ITT approach, the NMA revealed that AL was more efficacious than ASAQ, but the difference was not statistical significant (706 participants, three randomised clinical trials (RCT); OR 1.25, 95%CI 0.78-2.00). Adverse events ranged from mild to moderate severity but were not directly attributed to drug intake.
conclusionACTs are still effective and safe in Cameroon; however, there are insufficient data on their efficacy, safety and tolerability, therefore more RCTs should be conducted, including novel ACTs.
