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

The current study is to determine the regulatory role of VEGF-A in cardiac angiogenesis following myocardial infarction (MI). Cardiac angiogenic response and temporal/spatial expression of VEGF-A/VEGF receptors (VEGFR) were examined at 1, 2, 6, 12 h and 1, 2, 3, 4, 7, 14, and 28 days postMI. We found that following MI, newly formed vessels first appeared at the border zone between noninfarcted and infarcted myocardium as early as day 3 and subsequently in the infarcted myocardium. Vascular density in the infarcted myocardium peaked at day 7 and then gradually declined. VEGF-A mRNA started to increase at the border zone at 2 h postMI, reached peak at 12 h, declined at day 1, and returned to normal levels at day 2 and thereafter. VEGF-A protein levels at the border zone were only increased during day 1 postMI. VEGF-A within the infarcted myocardium levels, however, was persistently suppressed postMI. VEGFR expression was significantly increased only at the border zone at day 1, but not in the later stages. The expression of VEGF-A/VEGFR remained unchanged in the noninfarcted myocardium. Thus, the early rise of VEGF-A/VEGFR at the border zone suggests that VEGF-A initiates the cardiac angiogenic response postMI, but short-lived VEGF-A/VEGFR activation at the border zone and consistently suppressed VEGF-A within the infarcted myocardium suggests that VEGF-A may not be crucial to the later stages of angiogenesis.
