Activity of antifilarial drugs on microfilaremia in the treatment of loiasis: a systematic review.
Synthesis in Parasites & vectors, 2025. 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
backgroundLoiasis, caused by the nematode/filaria Loa loa, presents a major health burden in Central and West Africa. Despite the growing recognition of loiasis' medical significance, current antifilarial drugs remain inadequate in terms of efficacy and safety, particularly for individuals with hypermicrofilaremia. This systematic review aims to evaluate the efficacy of antifilarial treatment regimens for reducing L. loa microfilaremia and provide guidance on treatment strategies.
methodsA systematic review was conducted to evaluate the efficacy of antifilarial treatment regimens on reducing L. loa microfilaremia. Data on the percentage reduction of microfilaremia from baseline to nadir were extracted for each treatment regimen.
resultsA total of 27 studies were included in the review, with treatment regimens involving albendazole (ALB), mebendazole (MBZ), ivermectin (IVM), diethylcarbamazine (DEC), levamisole, imatinib, and moxidectin, among others. ALB and MBZ showed dose- and duration-dependent efficacy, with extended treatment leading to up to a 98-100% microfilaremia reduction. IVM showed a dose-dependent effect, with single doses of 200-400 µg/kg reducing microfilaremia by 88-92%. DEC exhibited high efficacy, achieving up to a 100% microfilaremia reduction.
conclusionsAntifilarial drug efficacy against L. loa microfilaremia varies by dosage and treatment duration, with IVM and DEC demonstrating rapid, high efficacy but presenting safety concerns for hypermicrofilaremic individuals. ALB and MBZ show efficacy with extended treatment but are slower acting. Further research is needed to optimize treatment regimens and assess clinical outcomes beyond microfilaremia reduction.
