Receiver Operating Characteristic (ROC) Analysis of Progesterone as Predictor for Ongoing Pregnancy Rate at Day 7 and Day of hCG Administration
Time frame · Day 7, approximately Day 10 (hCG Administration)
Registry description
The influence of the progesterone level on the ongoing pregnancy rate (in relation to all randomized patients) was determined by means of the receiver operating characteristic (ROC) curve. Youden's Index (sensitivity + specificity -1) has a range of 0-1, with 0.5 indicating a random effect.
Percentage of Participants With Ongoing Pregnancy
Time frame · approximately 3.5 months from study start (at least 9 weeks after first positive pregnancy test)
Registry description
Ongoing pregnancy is defined as having a positive foetal heart action nine or more weeks after the first positive pregnancy test.
Number of Follicles at hCG Administration
Time frame · approximately day 10
Registry description
Number of follicles \>=17 mm diameter detected by pelvic ultrasound examination at day of hCG administration.
Average Follicle Diameter at hCG Administration
Time frame · approximately day 10
Number of Cumulus-oocyte Complexes Retrieved
Time frame · approximately day 12 after study start
Registry description
Cumulus-oocyte complexes are oocytes with surrounding cumulus cells.
Number of Pronuclear Oocytes
Time frame · approximately day 13 after study start
Registry description
Pronuclear oocytes are fertilized oocytes.
Number of Participants With Pronuclear Stage Oocytes at Each Quality Grade
Time frame · approximately day 13
Registry description
The count of participants with different quality grades of pronuclear stage oocytes is offered. Pronuclear stage oocytes are categorized into seven grades (0A, 0B, 1-5) representing different patterns of pronuclear morphology, according to the German Pronuclear Morphology Study Group. 0A is the highest quality oocyte and grade 5 is the lowest quality.
Participants can have pronuclear stage oocytes of different grades and therefore are counted more than once.
Number of Embryos Transferred
Time frame · approximately day 14
Registry description
Mean number of embryos transferred 2-3 days following oocyte retrieval.
Best Quality of an Embryo Transferred
Time frame · approximately day 14
Registry description
Embryo quality was measured by the following grades:
* Grade 1: Evenly sized cells, regular cleavage, no fragmentation
* Grade 2: Regular or slightly irregular cleavage, \<=20% fragmentation
* Grade 2.5: Regular or slightly irregular cleavage, \>20%and \<=50% fragmentation
* Grade 3: Irregular cleavage, \>50% fragmentation, \>1 intact cell
* Grade 4: Extensive fragmentation, only 1 cell intact
* Grade 5: Totally fragmented, no viable cells.
Grade 1 represents the healthiest embryos and Grade 5 embryos are not viable.
Number of Frozen Oocytes at Pronuclear Stage
Time frame · approximately day 14
Registry description
No more than three normally developed embryos were transferred 2-3 days after oocyte retrieval. Other normally developed embryos were frozen.
Endometrial Thickness on Day of hCG Administration
Time frame · approximately day 10
Registry description
Endometrial thickness was assessed by pelvic ultrasound on the day of hCG administration.
Estradiol (E2) Levels on Day of hCG Administration
Time frame · approximately day 10
Percentage of Participants With Successful Embryo Transfer
Time frame · approximately day 18
Number of Days Stimulated With Gonadotrophins
Time frame · Day 1 up to Day 12
Registry description
Number of days in which gonadotrophins were administered until hCG criteria were met. If hCG criteria were not met by day 13, the participant was withdrawn from the study.
Number of Ampoules of Gonadotrophins Used
Time frame · Day 1 up to Day 12
Registry description
Number of ampoules of gonadotrophins used with the goal of reaching hCG criteria. Each ampoule contained 75 IU of either menotrophin or follitrophin alpha.
Percentage of Participants With Clinical Pregnancy 6 Weeks After the First Positive Pregnancy Test
Time frame · approximately 2.5 months from start of study, 6 weeks after first positive pregnancy test
Registry description
A pelvic ultrasound scan was performed approximately 6 weeks after the first positive pregnancy test and the presence of an active foetal heart action indicated a clinical pregnancy.
Summary of Pregnancy Outcome
Time frame · up to 10 months
Registry description
Pregnancy outcomes were reported at the optional long-term follow up visit.
