What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

What this could lead to

If successful, this could show that giving clot-busting drugs later than currently recommended is safe and effective, potentially expanding treatment options for many stroke patients.

What could go wrong

This is an observational study, not a controlled trial, so results may be influenced by other factors. It cannot prove cause and effect, and the risks of bleeding from late treatment are still unknown.
