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

backgroundProprotein Convertase Subtilisin/Kexin Type 9 (PCSK9) has been implicated in vascular inflammation beyond its action on LDL-C degradation. We investigated whether PCSK9 may exacerbate proinflammatory signaling of M1 macrophages and if its neutralization with alirocumab could attenuate this effect and plaque progression by LDL-C independent mechanisms.

resultsAlirocumab reduced plaque lesion (0.42-fold;

conclusionsPCSK9 may be released in parallel to proinflammatory factors such as hsCRP and FGF-23 in patients with ACS, independently of LDL-C levels. PCSK9 may directly promote macrophage-driven inflammatory responses through the TLR4-NFκB-NLRP3 signaling, but its neutralization with alirocumab attenuated this inflammatory axis and limited atherosclerotic progression, supporting an anti-inflammatory benefit secondary to PCSK9 inhibition.
