This paper on #furosemide treatment of #preterm infants is a great RCT, but I think there is a common misunderstanding, from reading comments like "Yes, I know furo is not working!".
The RCT was done to look into furosemide safety, not efficacy.
I am also sceptical about furosemide and BPD prevention, would be too good to be true, but we would need a much larger trial to look into that question.
