What this trial measures
- Change in prostaglandin E2 (PGE2)Baseline to 6 weeks
Assessed by repeated tissue sampling of the endometrium and compared between treatment and observation groups. A linear mixed-effects model (LMM) will be used to compare the change in PGE2 levels obtained from paired endometrial sampling between two groups of patients (aspirin versus \[vs.\] no aspirin). The continuous time that elapses between sampling will be assessed together with the binary patient group (aspirin vs. no aspirin) to investigate the change in continuous PGE2 measurement.
