Analyzing Dependence Structure Of Thyroid Hormones: A Copula Approach, Burcu Üçer
Analyzing Dependence Structure Of Thyroid Hormones: A Copula Approach, Burcu Üçer
Turkish Journal of Medical Sciences
To model the level and structure of the dependence between thyroid hormones by using the copula approach. Materials and methods: Dependence models were constructed with the help of copula functions explaining the relationships between thyroid hormones for the data supplied by Dokuz Eylül University's Faculty of Medicine's endocrine laboratory. For this purpose, 684 patients aged 0-85 were examined. Results: Results indicated that none of the pairs of thyroid hormones exhibited a tail dependence structure; however, valid models exhibited a symmetric dependence structure. The findings implied that both the T3 and T4 levels had a significant dependence structure with TSH levels. …

Turkish Journal of Medical Sciences
To compare the effects of 2 different anesthetic techniques used for oocyte retrieval. Comparison was made based on the number of retrieved and fertilized oocytes, metaphase 2 (M2, mature) oocytes, and transferred embryos, as well as fertilization, pregnancy, and live birth rates. Ultrasound-guided transvaginal oocyte retrieval for in vitro fertilization is one of the most common minor surgical procedures. Despite this, it is stressful and painful for the patient; most patients request sedation and/or pain relief. Propofol, which is frequently used for general anesthesia in such procedures, has been suspected to damage oocytes. Materials and methods: Results from 70 patients …
