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

backgroundCardiac lymphatics play an important role in myocardial edema and inflammation, however, the heterogeneity of cardiac lymphatic endothelial cells (LECs) and their biological functions have rarely been investigated.

methodsThis study integrated single-cell sequencing data and spatial transcriptome data from mouse heart tissue at different time points post-myocardial infarction (MI), and then revealed LECs heterogeneity and biological functions by clustering, spatial localization, cell trajectory, and Cell-Chat analyses.

resultsFour transcriptionally distinct subtypes of LECs were identified and localized in space. Cardiac LEC subgroups were found to be localized in different zones of infarcted heart related to different functions. LEC capillary III (LEC CaIII) may be involved in the direct regulation of myocardial injuries in an infarcted zone (IZ) from the perspective of metabolic stress, while LEC CaII may be related to the rapid immune inflammatory responses of the border zone (BZ) in the early stage of MI. LEC CaI, as well as LEC collection mainly participate in the regulation of myocardial tissue edema resolution in the middle and late stages post-MI. Cell trajectory and Cell-Chat analyses further identified that LECs may regulate myocardial edema through Aquaporin 1, and might affect the infiltration of macrophages through the galectin-9 (Gal-9)-CD44 pathway.

conclusionThis study revealed the dynamic transcriptional heterogeneity distribution of LECs in different regions of the infarcted heart, and these LECs formed different functional subgroups that might exhibit different bioeffects in myocardial tissue post-MI.
