Molecular Surveillance of Malaria in Nigeria Reveals a Low Frequency of Antimalarial Resistance Markers and Clonal Expansion of Chloroquine-Sensitive Infections.
Article in Open forum infectious diseases, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper, 1 of them a synthesis 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
Background: The success of malaria elimination in sub-Saharan Africa rests largely on the sustained efficacies of the chemointerventions used in malaria treatment and chemoprophylaxis in the highest-burden countries such as Nigeria. Data on the impact of these interventions can guide policy for sustained malaria control toward elimination. We report the complexity of infection (number of genetically distinct same-species parasite strains observed in an infection) and genetic diversity of Methods: We used targeted amplicon sequencing techniques to analyze 895 Results: Overall, infections were highly complex, with approximately 30% of these having more than a single genetically distinct parasite clone. Furthermore, 55.1% of the parasite isolates carried wild type alleles of the chloroquine transporter gene Conclusions: Chloroquine sensitivity at the molecular level is now dominant in Nigeria, while antifolate resistance persists. Enhanced molecular surveillance of drug resistance-associated loci will serve as an early warning to safeguard the efficacy of chemointerventions in Nigeria.
