Cosmc is required for T cell persistence in the periphery.
Article in Glycobiology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
T lymphocytes, a key arm of adaptive immunity, are known to dynamically regulate O-glycosylation during T cell maturation and when responding to stimuli; however, the direct role of O-glycans in T cell maturation remains largely unknown. Using a conditional knockout of the gene (C1GalT1C1 or Cosmc) encoding the specific chaperone Cosmc, we generated mice whose T cells lack extended O-glycans (T cell conditional Cosmc knock out or TCKO mice) and homogeneously express the truncated Tn antigen. Loss of Cosmc is highly deleterious to T cell persistence, with near-complete elimination of Cosmc-null T cells from spleen and lymph nodes. Total T cell counts are 20% of wild type (WT), among which only 5% express the truncated glycans, with the remaining 95% consisting of escapers from Cre-mediated recombination. TCKO thymocytes were able to complete thymic maturation but failed to populate the secondary lymphoid organs both natively and upon adoptive transfer to WT recipients. Our results demonstrate that extended O-glycosylation is required for the establishment and maintenance of the peripheral T cell population.
