Outcome improvement for anaemia and iron deficiency in enhanced recovery after surgery (ERAS) hip and knee arthroplasty: a descriptive analysis
Authors' conclusion
Conventional randomised trials with single or composite "hard" endpoints are at risk of being inconclusive or underpowered due to a considerable burden of other patient-related risk factors and with postoperative complications which may not be modifiable by correction of IDA per se.
