Enhancing safety of rapid and accurate malaria diagnosis in patients at risk for viral haemorrhagic fever.
Article in Malaria journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundMalaria and viral haemorrhagic fever (VHF) have overlapping symptomatology, creating clinical and diagnostic challenges within, and in travellers returning from, co-endemic areas. Rapid and accurate malaria diagnosis is critical, yet complicated by safety measures required for VHF.
methodsDiagnostic accuracies of the rapid Alethia Malaria loop-mediated isothermal amplification (LAMP) assay and EasyNAT Malaria cross-primer assay (CPA) were assessed for the detection of malaria in whole blood mixed with guanidine isothiocyanate (GITC)-based virucidal DNA/RNA Shield buffer.
resultsBoth the LAMP assay and the CPA performed excellent and detected DNA of Plasmodium spp. in all 47 mixtures. All mixtures without Plasmodium spp. DNA (n = 5) tested negative in both assays. Technical detection limit of both assays for P. falciparum was between 0.005 and 0.0005 parasites per microlitre of mixture.
conclusionsRapid and accurate malaria diagnosis remains possible on whole blood mixed with this virucidal buffer. The buffer is available in blood collection tubes, which allows for enhanced safety of sample handling from bedside to bench. These tubes can be used in patients with high suspicion of malaria, but in whom VHF cannot be completely excluded.
