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

backgroundCalcium (Ca

methodsJunctophilin expression was assayed in human and mouse CFs using reverse transcription quantitative polymerase chain reaction, Western blotting, and immunofluorescence. To investigate the functional role of Jph2 in CFs, we assessed Ca

resultsJph2 was identified as the only junctophilin expressed in CFs and acutely upregulated in response to myocardial infarction. Cellular and RNA sequencing analyses revealed that isolated Jph2-deficient CFs exhibited impaired fibroblast activation, reduced extracellular matrix production, and diminished expression of VEGFA (vascular endothelial growth factor A), VEGFB, and VEGFC after TGFβ treatment. In vivo, Jph2

conclusionsOur results demonstrate that Jph2 is required in CFs to orchestrate Ca
