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

Sinus node dysfunction, a prevalent arrhythmia in aging populations, is characterized by fibrosis and loss of pacemaker activity, necessitating pacemaker implantation. Current therapies fail to reverse the underlying pathology. Small extracellular vesicles derived from human induced pluripotent stem cells possess regenerative potential but lack targeted delivery. Here, we engineer platelet membrane-fused vesicles that synergistically combine collagen targeting for ischemic injury homing with immune evasion. In a rat model of sinus node dysfunction, these modified vesicles exhibit 3.1-fold higher accumulation in the sinoatrial node compared to unmodified vesicles, resulting in a 63% reduction in fibrosis and significant restoration of heart rate and intrinsic pacemaker function. The vesicles mitigate fibroblast activation and protect cardiomyocytes from oxidative stress. This study establishes a targeted, cell-free nanotherapeutic platform for resolving fibrosis and electrophysiological dysfunction in sinus node disease.
