1 · What the graph read from 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.

2 · The registry

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

A malaria vaccine targeting Plasmodium falciparum remains a strategic goal for malaria control. If a polyvalent vaccine is to be developed, its subunits would probably be chosen based on immunogenicity (concentration of elicited antibodies) and associations of selected antigens with protection. We propose an additional possible selection criterion for the inclusion of subunit antigens; that is, coordination between elicited antibodies. For the quantitative estimation of this coordination, we developed a malaria serological map (MSM). Construction of the MSM was based on three categories of variables: (i) malaria antigens, (ii) total IgG and IgG subclasses, (iii) different sources of plasma. To validate the MSM, in this study, we used four malaria antigens (AMA1, MSP2-3D7, MSP2-FC27 and Pf332-C231) and re-grouped the plasma samples into five pairs of subsets based on age, gender, residence, HbAS and malaria morbidity in 9 years. The plasma total IgG and IgG subclasses to the test antigens were measured, and the whole material was used for the MSM construction. Most of the variables in the MSM were previously tested and their associations with malaria morbidity are known. The coordination of response to each antigens pair in the MSM was quantified as the correlation rate (CR = overall number of significant correlations/total number of correlations × 100 %). Unexpectedly, the results showed that low CRs were mostly associated with variables linked with malaria protection and the antigen eliciting the least CRs was the one associated with protection. The MSM is, thus, of potential value for vaccine design and understanding of malaria natural immunity.
