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

Adipose-derived stem cell exosomes (ADSC-EXOs) serve as cell-free therapy, transporting signaling molecules that modulate adipose plasticity. However, the precise molecular mechanisms involved remain unclear. We used a high-fat diet-induced mouse obesity model and an MDI-induced 3T3-L1 cell differentiation model. We found that ADSC-EXOs improved systemic glucose and lipid metabolism, decreased PDCD4 and white adipocyte marker expression, and increased brown adipocyte marker expression along with the activation of the LXR-α/Akt pathway in inguinal adipose tissue. miR-21a-5p mimic or siPDCD4 transfection in 3T3-L1 cells recapitulated these effects, reducing lipid accumulation and promoting adipocyte browning, whereas PDCD4 overexpression produced the opposite effects. Mechanistically, miR-21a-5p directly targeted the 3' UTR of PDCD4. These findings indicate that ADSC-EXOs facilitate white fat browning through the miR-21a-5p/PDCD4 axis and thus activate the LXR-α/Akt signaling pathway, offering a potential therapeutic strategy for obesity-related metabolic dysfunction.
