Pre-existing and early cellular immune factors correlate with functionally complete protection against primary controlled human SARS-CoV-2 infection.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Identifying host factors that mediate protection against newly-emergent viruses is needed for improved pandemic preparedness. Here, we analysed pre- and early post-exposure immune factors associated with resisting SARS-CoV-2 infection after human challenge in seronegative individuals, using multiplex protein, cytometric and RNA sequencing approaches in the nasopharynx and circulation. Pre-existing cross-reactive antibodies correlate poorly with clinical outcome. Instead, protection is associated with heightened nasopharyngeal CCL13 levels locally produced by conventional dendritic cells and monocytes, along with cross-reactive T cells and less differentiated NK cells. Conditional independence network analysis implicates nasal CCL13 as the central node connected to pre-existing non-structural protein-specific T cells by CD1c
