“…Some previous studies have suggested discriminatory progesterone levels as low as 21.4 and as high as 82.5 nmol/l for predicting pregnancy in ICSI cycles [10][11][12] . The main drive for progesterone production comes from continuing stimulation of the corpora luteal by HCG.…”

Background: Intra cytoplasmic sperm injection (ICSI) is one of the effective treatments in women with fertility problems; however, there are no approved predictors for pregnancy till the present moment. We aimed to evaluate the role of progesterone and endometrium pattern in predicting pregnancy in ICSI cycles. Patients and Methods: The study included 200 women who were treated in Al-Shatby Hospital in (ICSI) Unit from January 2017 to October 2018. They underwent one super ovulation protocol which was gonadotrophin in which releasing hormone progesterone was measured in the 14 th day; while ultrasound was performed in the 3rd day and in the day of HCG administration. Results and Conclusion: Progesterone with a cutoff point of 27 ng/mol is a significant predictor of pregnancy in ICSI cycle. However, neither endometrial thickness nor pattern was a significant predictor of pregnancy.

“…Using the meta‐analysis performed by Dukic & Gatsonis () as a starting point, we identified articles that evaluate the properties of progesterone level as a diagnostic test for the viability of a pregnancy. Among the cited papers, we found that Gelder, Boots, & Younger (), Grosskinsky et al (), Ledger, Sweeting, & Chatterjee (), O'Leary et al (), Peterson et al (), Riss, Radivojevic, & Bieglmayer (), Stewart, Nazar‐Stewart, & Toivola (), and Witt et al () provide a graphical display of their raw data, most often, some form of scatter plots where individual progesterone values can be read. In addition, we found similar displays in Dumps et al (), Florio et al (), and Hanita & Hanisah ().…”

“…Contrarily to Harbord et al () and Arends et al () who use frequency table data, we assume that raw data are available. As a case study, we extract such raw data from figures in published articles, namely Dumps et al (), Florio et al (), Gelder, Boots, & Younger (), Grosskinsky et al (), Hanita & Hanisah (), Ledger, Sweeting, & Chatterjee (), O'Leary et al (), Peterson et al (), Riss, Radivojevic, & Bieglmayer (), Stewart, Nazar‐Stewart, & Toivola (), and Witt et al (). Our approach has the advantage of keeping track of the scale upon which the diagnostic is based.…”

The receiver operating characteristic (ROC) curve can be used to evaluate the properties of a diagnostic test from the distribution of a variable on the healthy and diseased populations. The minimum averaged mean squared error (MAMSE) weights were developed to handle data from different sources by adjusting the relative contribution of each data source. The authors use the MAMSE weights to infer the ROC curve of a diagnostic test based on raw data from multiple studies. The proposed estimates are consistent and Monte Carlo simulations show favourable finite sample performance. The method is illustrated in a case study where progesterone level is used to detect ectopic pregnancies and abortions from other natural causes.

“…The value of this approach compared with standard evaluation (observation, selective diagnostic laparoscopy, serial PhCG levels) has not been determined. 74 Likewise, the prognosis of low-progesterone ectopic pregnancies is not known; these eciopic pregnancies may be destined for tubal abortion' or regression.…”

I This article is the first in a twopart comprehensive review of the current state of knowledge and technology available for the diagnosis of ectopic pregnancy. These articles are focused on the diagnostic approach relevant to emergency medicine. Part I addresses the clinical and laboratory evaluation of the patient at risk for ectopic pregnancy. Part 11 (page 1090) discusses the use of diagnostic procedures (including laparoscopy and culdocentesis) and imaging studies.To obtain resource material for these reviews, a MEDLINE English-language literature search was performed for the years 1990-1994. The following key words were used: ectopic pregnancy, and the subset terms diagnosis, ultrasonography , human chorionic gonadotropin (hCG), progesterone, culdocentesis, and laparoscopy . Further references were identified from the bibliographies of the articles identified by the MEDLINE search. These sources were combined with similar more selective searches performed over the years 1986-1990.
