Prophylactic platelet transfusion prior to surgery vs no prophylactic platelet transfusion prior to surgery

All‐cause mortality within 30 days of surgery · people with a low platelet count

It is very uncertain whether prophylactic platelet transfusion prior to surgery changes all‐cause mortality within 30 days of surgery compared with no prophylactic platelet transfusion prior to surgery (very low certainty).
