Cryptosporidium secreted proteins form a complex layered interface with the host cell.
Article in PLoS pathogens, 2026. 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
Cryptosporidium parvum, one of the leading causes of diarrheal death in children, remodels its infection site through secreted effector proteins. Several of them accumulate at the host-parasite interface, forming a complex structure whose function and importance for infection remain poorly understood. Here, we localized and functionally characterized the putative dense granule protein DG8. We confirmed the protein to be in the dense granules, forming a ring structure once secreted at the host-parasite interface. Deletion of DG8 showed reduced infection in mice in vivo and early defect in vitro, revealing the importance of DG8 for parasite fitness. Additional secreted proteins were identified as potential partners, among which SG4, a small granule protein, was shown to partially co-localize with DG8. Applying ultrastructure expansion microscopy on intestinal sections with newly generated antibodies against DG8 and SG4, we could precisely position the ring structure above the electron-dense band, around the feeder organelle at the base of the parasitophorous vacuole membrane with an unprecedent resolution. Altogether, better visualization and understanding of the host-parasite interface through expanded intestinal tissue and effectors characterization reveal a complex and essential layered host-parasite interface.
