The authors would like to apologize for an error in Table I of the above manuscript, describing the ESHRE Bologna criteria. Table I was originally based on Ferraretti and Gianaroli, 2014 rather than the original Bologna criteria article (Ferraretti et al., 2011). Ferraretti and Gianaroli states that cancelled cycles should be included in the determination of previous episodes of poor ovarian response (POR). Although the use of cancelled cycles had been discussed for inclusion as a criterion to identify previous episodes of POR, this was not included in the final 2011 consensus. A revised version of Table I can be found below.
Table I.
The ESHRE Bologna criteria and the ESPART trial inclusion criteria for POR.
| 2011 ESHRE Bologna criteria, Ferraretti et al. (2011) | ESPART POR inclusion criteria* |
|---|---|
| Advanced maternal age (≥40 years) or any other risk factor | Advanced maternal age (≥40–<41 years, i.e. patients between their 40th and 41st birthday) |
| A previous POR (≤3 oocytes with a conventional stimulation protocol) | Previous ART cycle with ≤3 oocytes retrieved with a conventional stimulation protocol |
| An abnormal ORT (AFC <5–7 follicles or AMH <0.5–1.1 ng/ml) | An abnormal ORT (AMH 0.12–1.3 ng/ml; measured by AMH GEN II ELISA, Beckman Coulter, Inc., High Wycombe, UK) La Marca and Sunkara (2014) |
| In the absence of advanced maternal age or abnormal ORT, two previous episodes of POR after maximal stimulation | Patients with two previous episodes of POR after maximal stimulation were excluded |
*Two out of three POR inclusion criteria needed to be met for inclusion in the ESPART trial.
AFC, antral follicle count; ORT, ovarian reserve test; POR, poor ovarian response; ESPART, Efficacy and Safety of Pergoveris in Assisted Reproductive Technology.
The authors would like to reassure readers that this does not affect any other content of the article.
