Heme processing in the malaria parasite, Plasmodium falciparum: a time-dependent basal-level analysis.
Article in Communications biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Malaria is a deadly disease for which therapeutic options are threatened by the rise of antimalarial resistance. Inhibiting the formation of hemozoin (the product of heme detoxification) in the digestive vacuole (DV) is the mechanism of action of numerous antimalarial drugs, including those in development as new therapies. This drug target remains attractive as hemozoin is an abiotic and non-mutable molecule, unique to the parasite. The underlying parasite biology of the heme detoxification pathway is complex and requires a deeper understanding. This study focuses on the DV of Plasmodium falciparum, utilizing confocal microscopy, immunofluorescence, immunoblotting and cellular fractionation techniques to study its native state over time. Using parameters such as the uptake into and growth of the DV, relative abundance of plasmepsins (PMs) I and IV as well as basal levels of hemoglobin, heme and hemozoin, it was found that DV physiology in chloroquine (CQ)-sensitive NF54 follows three distinct developmental phases: the lag-type growth (20 to 28 h), rapid growth phase (28 to 40 h) and the plateau (40 to 48 h). These phases hold specific characteristics with respect to the investigated parameters. In addition, key differences between CQ-sensitive NF54 and CQ-resistant Dd2 parasites were observed.
