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

backgroundEpidemiological studies have consistently associated cytomegalovirus (CMV) seropositivity with adverse cardiovascular outcomes. However, the mechanisms by which cytomegalovirus infection impacts pathophysiology in the heart remain poorly understood. In this study, we sought to dissect how latent murine cytomegalovirus infection impacts cardiac immune cell dynamics at steady-state and during postmyocardial infarction (MI) repair.

methodsExperimental MI studies were conducted in C57BL/6J mice previously infected with murine cytomegalovirus. In situ inflammatory responses were characterized by spectral flow cytometry, bulk and single-cell RNA/T-cell receptor (TCR) sequencing, whereas cardiac function was monitored by echocardiography and cardiac magnetic resonance imaging. Moreover, we retrospectively assessed the cytomegalovirus serostatus and associated T-cell expansions in a well-characterized patient cohort with longitudinal cardiac magnetic resonance imaging data available and performed bulk TCR sequencing on peripheral blood and myocardial samples to identify cytomegalovirus-specific TCRs.

resultsOur findings show that exposure to murine cytomegalovirus induces long-term changes in the cardiac transcriptional profile and alterations in various cardiac-resident immune cell populations, including the establishment of virus-specific memory CD8

conclusionsOur findings demonstrate that latent cytomegalovirus infection leads to long-term changes in the cardiac microenvironment, which ultimately impair post-MI healing outcomes.
