Late selective reduction of TRAP mass clinical trials

TRAP Intervention STudy: Early Versus Late Intervention for Twin Reversed Arterial Perfusion Sequence

This study looks at the best time to treat a rare twin pregnancy problem called TRAP sequence. We're comparing treating it early (12-14 weeks) versus later (16-19 weeks) to see which approach works better for the healthy twin. It's a randomised trial, meaning timing is decided by chance.
