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

Stem cell-derived extracellular vesicles (EVs) hold significant promise for tissue regeneration due to their potent therapeutic cargo. However, their clinical translation is hindered by rapid clearance from target sites following systemic or local administration, leading to inefficient delivery and limited therapeutic efficacy. To overcome this critical challenge, we developed a click-crosslinked dopamine-functionalized hyaluronic acid hydrogel system (Dopa-HA) for the sustained and localized delivery of EVs. Dopamine was chemically conjugated to the click-crosslinked hydrogel to enhance the robust immobilization of EVs. The physicochemical properties of this hydrogel system were subsequently characterized, including dopamine functionalization degree, rheological behavior, degradation rates, and
