Diagnostic delay inducing severe imported falciparum malaria: a time-sensitivity comparison of two imported cases during COVID-19 co-circulation.
Article in Malaria journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundThe COVID-19 pandemic created novel diagnostic challenges for imported malaria due to overlapping symptoms and prioritized SARS-CoV-2 screening. This report presents a critical comparative analysis demonstrating how diagnostic delays during co-circulation directly impact malaria severity-an underreported phenomenon with significant clinical implications. CASE PRESENTATION: Two male patients returning from Africa (Nigeria and Côte d'Ivoire) developed fever during mandatory COVID-19 quarantine in Shanghai, China (2021). Both initially tested negative for SARS-CoV-2. Case 1 experienced a 96-h diagnostic delay, progressing to severe falciparum malaria with delirium, thrombocytopenia (33 × 10⁹/L), and acute kidney injury (creatinine 278 μmol/L), requiring intensive care. Case 2 was diagnosed within 24 h via rapid diagnostic test and microscopy, receiving immediate artesunate treatment without severe complications.
conclusionsDiagnostic delay directly impacts severe malaria risk during COVID-19 co-circulation. Parallel testing for both pathogens in febrile travelers from endemic areas is critical. The proposed "48-Hour Three-Tier Diagnostic Response System" should shorten the diagnostic window.
