The Role of Haemoglobin Variants and Red Blood Cell Polymorphisms in Asymptomatic Malaria: A Cross-Sectional Study.
Article in Health science reports, 2026. 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
Background and Aims: Human phenotypes, particularly blood group polymorphisms (ABO) and haemoglobin variants (HbAA and HbAS), have been widely studied in relation to clinical malaria. However, their role in asymptomatic malaria remains underexplored. This study therefore, investigated the association of these phenotypic variants with the burden of asymptomatic malaria among Ghanaians. Methodology: Community members without clinical signs of malaria were recruited from four endemic communities. Whole blood samples were screened for Results: Haemoglobin variants ( Conclusion: This study found a high prevalence of asymptomatic malaria among community members. Haemoglobin variants and ABO blood group polymorphisms were associated with asymptomatic malaria, with HbAA showing significantly higher odds of infection. Although higher odds were observed among individuals with O Rh D-positive, O/HbAA, and B/HbAS phenotypes, these associations were not statistically significant. These findings highlight the complex role of host genetic factors in asymptomatic malaria carriage and underscore the need for further studies with larger sample sizes to clarify these associations.
